Postproxy MCP Server

Postproxy MCP Server

MCP (Model Context Protocol) server for integrating Postproxy API with Claude Code. This server provides tools for publishing posts, checking statuses, and managing social media profiles through Claude Code.

Installation

Global Installation

npm install -g postproxy-mcp

Local Installation

npm install postproxy-mcp

Claude Code stores MCP server configuration under ~/.claude/plugins/. After installing postproxy-mcp, Claude will automatically detect the server on restart.

Configuration

Register MCP Server

After installing postproxy-mcp, register it with Claude Code using the claude mcp add command:

claude mcp add --transport stdio postproxy-mcp --env POSTPROXY_API_KEY=your-api-key --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api -- postproxy-mcp

Replace your-api-key with your actual Postproxy API key.

The configuration will be automatically saved to ~/.claude/plugins/. After running this command:

1. Restart your Claude Code session
2. Test the connection by asking Claude: "Check my Postproxy authentication status"
3. If tools are available, Claude will be able to use them automatically

Alternative: Interactive Setup

For non-technical users, you can use the interactive setup command:

postproxy-mcp setup

or

postproxy-mcp-setup

This will guide you through the setup process step by step and register the server using claude mcp add automatically.

  "profile_groups_count": 2
}

Account Overview

summary_get

Answer "what's the status?" in one call — an activity snapshot for a time window instead of separate history_list / comments_list / dm_chats_list round trips.

Parameters:

• window (string, optional): 24h (default), 7d, or 30d
• from (string, optional): ISO 8601 timestamp or bare date starting an explicit range. Overrides window, and the *_previous counts come back null
• to (string, optional): End of the explicit range. Defaults to now when only from is given
• profile_group_id (string, optional): Report on a single group. Omit to cover every group the key can reach

Returns:

{
  "window": {
    "label": "24h",
    "from": "2026-08-17T09:00:00Z",
    "to": "2026-08-18T09:00:00Z",
    "previous_from": "2026-08-16T09:00:00Z",
    "backlog_from": "2026-07-19T09:00:00Z"
  },
  "posts": {
    "published": 4,
    "published_previous": 3,
    "failed": 1,
    "scheduled_ahead": 6,
    "next_scheduled_at": "2026-08-18T14:00:00Z",
    "by_platform": { "instagram": { "published": 4, "failed": 0 } }
  },
  "engagement": {
    "total": { "impressions": 48210, "likes": 1204 },
    "by_platform": { "instagram": { "impressions": 31002, "likes": 900 } },
    "posts_with_insights": 14
  },
  "comments": { "received": 96, "received_previous": 71, "awaiting_reply": 12, "by_platform": { "instagram": 61 } },
  "reviews": { "received": 7, "received_previous": 4, "awaiting_reply": 3 },
  "dms": { "inbound": 41, "outbound": 33, "chats_awaiting_reply": 5, "reply_window_closing": 2 },
  "api": { "calls": 812, "calls_previous": 640 }
}

Notes:

• Post counts are posts, so a post sent to three networks counts once and a thread counts once. by_platform counts per-network deliveries, so a 3-item X thread is 3 under twitter.
• engagement is lifetime-to-date for posts published in the window, not engagement earned during it — it sums each post's newest stats snapshot. A post published minutes ago may have no snapshot yet and won't be in posts_with_insights. Keys are the normalized metrics listed in Stats Fields by Platform.
• The awaiting_reply counts describe current state, not the window — they don't change when you change window. They look back 30 days, returned as window.backlog_from. A comment counts as replied only when the reply came from you (via Postproxy or the profile itself); chats_awaiting_reply is derived from message timestamps, since Postproxy has no read/unread state.
• reply_window_closing counts chats with under 6 hours of their 24h messaging window left. Networks without a window (Telegram, Bluesky) are excluded.
• engagement is null when insights are off for the account; dms is null when DMs are off.
• Scoped like every other tool: a group-scoped key reports only its group.

Profile Management

profile_groups_list

List all profile groups accessible with your API key. Profile groups are organizational containers (e.g. per brand or client) that hold related profiles. Use a group's id to filter profiles_list by profile_group_id.

Parameters: None

Returns:

{
  "profile_groups": [
    {
      "id": "grp123abc",
      "name": "Main Brand",
      "profiles_count": 4
    }
  ]
}

profiles_list

List all available social media profiles for posting.

Parameters:

• profile_group_id (string, optional): If provided, only profiles in this group are returned (use profile_groups_list to find group IDs)

Returns:

{
  "profiles": [
    {
      "id": "profile-123",
      "name": "My Twitter Account",
      "platform": "twitter",
      "profile_group_id": "group-abc"
    }
  ]
}

profiles_placements

List available placements for a profile. For Facebook profiles, placements are business pages. For LinkedIn profiles, placements include the personal profile and organizations. For Pinterest profiles, placements are boards. For Telegram profiles, placements are channels the bot can post to. For Google Business profiles, placements are locations, returned as full resource paths (accounts/X/locations/Y) to pass as location_id. Available for facebook, linkedin, pinterest, telegram, and google_business profiles.

Parameters:

• profile_id (string, required): Profile hashid

Returns (LinkedIn example):

{
  "placements": [
    {
      "id": null,
      "name": "Personal Profile"
    },
    {
      "id": "108520199",
      "name": "Acme Marketing"
    }
  ]
}

Notes:

• If no placement is specified when creating a post:
  • LinkedIn: defaults to the personal profile
  • Facebook: defaults to a random connected page (if only one page is connected, no need to set a placement ID)
  • Pinterest: it fails
  • Telegram: it fails — chat_id is required on every post
  • Google Business: it fails — location_id is required on every post and on every google_business_* tool

profiles_stats

Get the follower/engagement timeseries for a profile. Snapshots are captured roughly every 23 hours, so you can plot follower growth and other trends over time. The stats fields are platform-native (not normalized) — see Stats Fields by Platform in the post_stats section for shape and add-on profile-level keys (followers_count, followersCount, etc.) per network.

Parameters:

• profile_id (string, required): Profile hashid
• placement_id (string, conditional): Required for facebook, linkedin, telegram, and google_business profiles. Get it from profiles_placements. Omit for instagram, threads, youtube, twitter, tiktok, pinterest, and bluesky.
• from (string, optional): ISO 8601 timestamp — only include snapshots recorded at or after this time
• to (string, optional): ISO 8601 timestamp — only include snapshots recorded at or before this time

Returns (LinkedIn example):

{
  "data": {
    "profile_id": "prof_li_001",
    "platform": "linkedin",
    "placement_id": "108520199",
    "records": [
      { "stats": { "followerCount": 4500, "shareCount": 8, "likeCount": 80 }, "recorded_at": "2026-05-09T08:00:00Z" },
      { "stats": { "followerCount": 4520, "shareCount": 9, "likeCount": 90 }, "recorded_at": "2026-05-10T08:00:00Z" }
    ]
  }
}

For non-placement networks (e.g. Bluesky), omit placement_id:

{
  "data": {
    "profile_id": "prof_bsky_001",
    "platform": "bluesky",
    "placement_id": null,
    "records": [
      { "stats": { "followersCount": 8800, "postsCount": 40 }, "recorded_at": "2026-05-09T08:00:00Z" }
    ]
  }
}

Parameters:

• queue_id (string, required): Queue ID

Returns:

{
  "next_slot": "2026-03-11T14:00:00Z"
}

Adding Posts to a Queue

When publishing a post with post_publish, you can add it to a queue instead of scheduling it manually:

• queue_id (string, optional): Queue ID to add the post to. The queue will automatically assign a timeslot. Do not use together with schedule.
• queue_priority (string, optional): Priority level: high, medium (default), or low. Higher priority posts get earlier timeslots.

Example:

{
  "content": "Queued post content",
  "profiles": ["twitter", "linkedin"],
  "queue_id": "q1abc",
  "queue_priority": "high"
}

Comment Management

comments_list

List comments on a published post. Returns paginated top-level comments with nested replies.

Parameters:

• post_id (string, required): Post ID
• profile_id (string, required): Profile ID to identify which platform's comments to retrieve
• page (number, optional): Page number, zero-indexed (default: 0)
• per_page (number, optional): Number of top-level comments per page (default: 20)
• from (string, optional): ISO 8601 date/time — only comments received at or after this point
• to (string, optional): ISO 8601 date/time — only comments received at or before this point

from/to filter on when Postproxy received the comment, not the platform's posted_at (which isn't always populated). A bare date such as 2026-03-25 means that date's start of day. The filter applies to top-level comments only — a comment in range still returns its full replies array.

Returns:

{
  "total": 42,
  "page": 0,
  "per_page": 20,
  "data": [
    {
      "id": "cmt_abc123",
      "external_id": "17858893269123456",
      "body": "Great post!",
      "status": "synced",
      "author_username": "someuser",
      "like_count": 3,
      "is_hidden": false,
      "posted_at": "2026-03-25T10:00:00.000Z",
      "replies": [
        {
          "id": "cmt_def456",
          "body": "Thanks!",
          "author_username": "author",
          "parent_external_id": "17858893269123456"
        }
      ]
    }
  ]
}

Comment objects may also include an attachments array (media on the comment — image, video, audio, gif, external, file), each with id, type, url, status, and external_id. Populated for Facebook, Threads, and Bluesky; Instagram, YouTube, and LinkedIn comments are text-only. The array is empty when there is no media.

comments_get

Get a single comment with its replies.

Parameters:

• post_id (string, required): Post ID
• comment_id (string, required): Comment ID (Postproxy ID or platform external ID)
• profile_id (string, required): Profile ID

comments_create

Create a comment or reply on a published post. The comment is published to the platform asynchronously.

Parameters:

  "id": "cmt_ghi789",
  "body": "Thanks for the feedback everyone!",
  "status": "pending",
  "external_id": null

Platform Support

Direct Messages

1:1 messaging (chats and messages) on DM-capable profiles. Supported on Facebook (Messenger), Instagram (DMs), Telegram (Bot DMs), and Bluesky. Outbound sends are processed asynchronously (returned with status: "pending"). Meta's 24h messaging window applies to Facebook/Instagram — a human replying to the participant's own inquiry can pass tag: "HUMAN_AGENT" to send outside it (up to 7 days, never for promotional or automated content); Telegram and Bluesky have no window.

dm_chats_list

List chats for a profile, ordered by most recent activity.

Parameters:

• profile_id (string, required): Profile ID (Facebook, Instagram, Telegram, or Bluesky)
• page (number, optional): Page number, zero-indexed (default: 0)
• per_page (number, optional): Items per page (default: 20)
• before / after (string, optional): ISO 8601 timestamp filters on last_message_at

dm_chat_create

Find or create a chat for a participant (idempotent — returns the existing chat if one exists). Use before messaging a participant the profile hasn't messaged yet.

Parameters:

• profile_id (string, required): Profile ID
• participant_external_id (string, required): Platform participant ID (IG-scoped user ID, Facebook PSID, Telegram user id, or Bluesky DID)
• participant_username (string, optional)
• participant_name (string, optional)

dm_chat_get

Get a single chat by Postproxy ID or platform external_conversation_id.

Parameters:

• chat_id (string, required): Chat ID or external conversation ID

dm_messages_list

List messages in a chat, most recent first.

Parameters:

• chat_id (string, required): Chat ID or external conversation ID
• page (number, optional): Page number, zero-indexed (default: 0)
• per_page (number, optional): Items per page (default: 20)
• direction (string, optional): inbound or outbound
• status (string, optional): Filter by message status

dm_message_send

Send an outbound message. Provide either body (text) or media (a single attachment), not both.

Parameters:

• chat_id (string, required): Chat ID or external conversation ID
• body (string, optional): Message text (required when media is empty)
• media (string[], optional): Up to one attachment as a URL or local file path. Not supported on Bluesky. (The remote/Worker MCP accepts URLs only.)
• tag (string, optional): HUMAN_AGENT to send outside the 24h window — extends it to 7 days from the participant's last inbound message (Facebook/Instagram only). Meta restricts it to a human replying to the participant's own inquiry; using it for marketing, offers, or automated re-engagement can get that Page / Instagram account's messaging capability suspended. Past 7 days Meta rejects the send and the message lands in status: failed with the platform error in error_details.
• reply_to_external_id (string, optional): Telegram only — message_id to thread under
• reply_markup (object, optional): Telegram only — inline/reply keyboard payload
• quick_replies (object[], optional): Facebook & Instagram only — up to 13 tappable chips above the participant's composer. Each { title, payload }.
• buttons (object[], optional): Facebook & Instagram only — up to 3 buttons attached to the message. Each { type: "web_url", title, url } or { type: "postback", title, payload }.
• card (object, optional): Facebook & Instagram only — extra fields for the card carrying buttons (subtitle, image_url, default_action). Requires buttons.

Quick replies and buttons

Facebook Messenger and Instagram Direct only — on Telegram use reply_markup instead (passing these returns a 422). Quick replies are ephemeral chips that vanish once one is tapped; buttons stay attached to the message in the thread.

{
  "chat_id": "chat_xyz789",
  "body": "What can I help with?",
  "quick_replies": [
    { "title": "Track order", "payload": "TRACK" },
    { "title": "Talk to support", "payload": "HELP" }
  ]
}

{
  "chat_id": "chat_xyz789",
  "body": "Nike Air Max",
  "card": { "subtitle": "$129 · Arriving Friday", "image_url": "https://cdn.example.com/shoe.png" },
  "buttons": [
    { "type": "web_url", "title": "Buy now", "url": "https://shop.example.com/p/air-max" },
    { "type": "postback", "title": "Notify me", "payload": "NOTIFY:air-max" }
  ]
}

Buttons are delivered as a Meta generic template whose element title is your body — that's where the 80-character cap comes from. Instagram is stricter than Messenger: it delivers quick replies only on a plain-text message, so quick_replies with media or with buttons returns 422 there.

Receiving taps: a tapped chip or button postback arrives as an inbound message carrying tapped_action: { "kind": "quick_reply" | "postback" | "callback_query", "payload": "...", "title": "..." }. Read it from dm_messages_list / dm_message_get instead of digging through platform_data. Instagram ice-breaker taps and Telegram callback queries normalize to the same field.

dm_message_get

Get a single message by Postproxy ID or platform external_id.

Parameters:

History

history_list

List recent post jobs.

Parameters:

• limit (number, optional): Maximum number of jobs to return (default: 10)

Returns:

{
  "jobs": [
    {
      "post_id": "job-123",
      "content": "Full post body as submitted...",
      "content_preview": "Post content preview...",
      "created_at": "2024-01-01T12:00:00Z",
      "overall_status": "complete",
      "status": "processed",
      "scheduled_at": "2024-01-02T09:00:00Z",
      "draft": false,
      "source": "postproxy",
      "queue_id": null,
      "platforms_count": 2,
      "platforms": [
        {
          "platform": "twitter",
          "status": "published",
          "url": "https://x.com/user/status/123"
        }
      ]
    }
  ]
}

scheduled_at is null for posts that were published immediately. status is the raw API status (draft, scheduled, processing, processed, …), while overall_status folds platform outcomes into a single verdict.

Note: Postproxy's /posts API does not return profile identity (profile ID or name) per platform — only the network. Use profiles_list to map networks to connected profiles.

Google Business Profile Management

These edit the Google business listing itself — hours, attributes, services, food menus, action links and profile photos — as opposed to publishing local posts to it (that's post_publish with platform google_business).

Three rules apply to every tool in this group:

1. location_id is always required. It's the full Google resource path accounts/X/locations/Y, returned by profiles_placements.
2. Updates are field-masked. Each write takes a fields array naming exactly what's being replaced. Anything named in fields but absent from the payload is cleared, and nested objects are replaced wholesale rather than merged. Always read before you patch.
3. Availability varies by category and region. Attributes, service lists, food menus and action link types differ per listing. List what's available first; a location that isn't eligible returns 422.

Payloads use Google's own shapes and camelCased keys in both directions, so a response can be sent straight back as a request body.

Typical flow

1. profiles_placements                    → get location_id
2. google_business_location_get           → read current state
3. google_business_attributes_available   → see what this listing accepts
4. google_business_attributes_update      → patch only what changed

Attribute value shapes

google_business_attributes_available returns a valueType per attribute, which decides the shape to send back:

attribute_mask defaults to exactly the names you send, so a partial update never clears attributes you left out.

Hours

Times accept either "09:00" / "09:00:00" strings or Google's { "hours": 9, "minutes": 0 } objects — both are normalized before the call. Read current hours from google_business_location_get; each block named in fields is replaced entirely.

{
  "fields": ["regularHours"],
  "regularHours": {
    "periods": [
      { "openDay": "MONDAY", "openTime": "09:00", "closeDay": "MONDAY", "closeTime": "18:00" }
    ]
  }
}

Media

Google downloads the file from media_url itself — there is no upload step, so the URL must be publicly reachable https (not a short-lived signed URL, not localhost). Images need at least 250×250 and at most 5MB. category defaults to ADDITIONAL; use COVER or LOGO only when you intend to change the profile header or logo.

Reading empty results

Google omits keys rather than returning empty values: a listing with no attributes returns { "name": "..." } with no attributes key at all, and the same applies to serviceItems, placeActionLinks and boolean flags like isPreferred. Treat absent as empty.

Analytics

Google Business location analytics come through the standard profiles_stats tool — pass the location_id as placement_id. Metrics are Search and Maps impressions (desktop and mobile), website clicks, call clicks, direction requests, conversations, bookings, food orders and food-menu clicks. Google Business has no follower count, and Google exposes no per-post analytics for local posts.

Example Prompts

Here are some example prompts you can use with Claude Code:
