Nabit Codex Plugin MCP Server

Nabit Video Recommendations 0.5.5

Six workflow skills and 31 composable MCP tools for product management, short-form video hook matching, trend tracking, opening analysis, collections, feedback, scheduling, and credit usage — powered by Nabit over remote Streamable HTTP MCP (https://nabit.ai/mcp) with OAuth 2.1 + PKCE. Your host agent understands the task and orchestrates the capabilities. Video production is not included.

Costs use the existing Nabit product prices, credit holds, settlement, refunds, quotas, and update budgets. No separate plugin wallet or surcharge is introduced. Existing product-only links keep their original boundaries; management and paid matching require explicit workspace consent. Ordinary updates preserve authorization. Reauthorize for workspace access only when you request a capability requiring that upgrade.

Workflow skills

• setup: account connection, permission range, and software updates.
• products: product context, URL preview, lookup, and product management.
• video-recommendation: current matching batches, comparisons, and daily digests.
• trending: existing product trends and requested tracking.
• library: details, opening explanations, collections, and explicit feedback.
• settings: usage, update/email settings, and host scheduling.

Provide product facts in your current conversation, or ask the agent to use an existing Nabit product. Current matching uses request_recommendations, get_recommendation_batch, and next_recommendation_batch. The compatibility get_video_recommendations tool reads the current existing matching batch, with a limit and exclusions. It requires workspace consent; old product-only grants receive WORKSPACE_CONSENT_REQUIRED instead of a misleading empty list. Daily digests read existing batches and do not start paid matching.

Playable references

render_video_recommendations displays an existing completed batch in compatible MCP UI hosts. Video access is short-lived, limited to the returned references, and stops when the Nabit grant is revoked. Browsers preserve the viewing link through sign-in. Codex hosts without MCP UI can use the bundled helper to produce a playable local HTML gallery; the workflow skill supplies the exact command. Rendering or refreshing a gallery does not start another paid batch.

Install in Codex from Git

codex plugin marketplace add https://github.com/Crimson-Pass/nabit-codex-plugin.git --ref main
codex plugin add nabit-video-recommendation@nabit-oauth

The package requests authentication during installation. If your Codex client does not open that flow, invoke Nabit in a conversation: the plugin starts the native connection action or runs the Codex login command when shell access is available. You sign in to your Nabit account, approve current workspace access, and approve permissions in the browser. Existing product-only grants remain restricted; product management and spending capabilities need explicit workspace consent. Only when the host cannot start it for you, run codex mcp login nabit manually. The plugin verifies the connection afterward; when the host cannot reload its tools, the bundled credential-managed Codex helper can continue the original request in the same conversation. Installation does not grant account access or create a schedule.

Connect via Streamable HTTP MCP (Claude Code, Cursor, VS Code, Codex)

Any MCP host supporting remote Streamable HTTP with OAuth 2.1 + PKCE can connect directly to https://nabit.ai/mcp:

• Claude Code:

  claude mcp add --transport http nabit https://nabit.ai/mcp
  

• Codex (tools-only without bundled skills):

  codex mcp add nabit --url https://nabit.ai/mcp
  codex mcp login nabit
  

• Cursor / VS Code / MCP JSON config:

  {
    "mcpServers": {
      "nabit": {
        "type": "streamable-http",
        "url": "https://nabit.ai/mcp"
      }
    }
  }
  

Update an existing Git installation

codex plugin marketplace upgrade nabit-oauth
codex plugin add nabit-video-recommendation@nabit-oauth

The first command refreshes the source. The second installs the refreshed package. Check the version reported by the install command, then start a new conversation. Updates are user-triggered, not silent automatic installs. They preserve existing OAuth authorization; sign in again if authentication fails or a legacy product grant needs an explicit workspace upgrade for current recommendations, credits or trends.

Migrate an older source

First check codex plugin marketplace list --json. If nabit-oauth uses a local folder or a previous Git URL, run:

codex plugin marketplace remove nabit-oauth
codex plugin marketplace add https://github.com/Crimson-Pass/nabit-codex-plugin.git --ref main
codex plugin add nabit-video-recommendation@nabit-oauth

This replaces the configured marketplace source while keeping the plugin name and MCP address. It does not revoke account authorization. Do not uninstall the plugin or delete credentials. If adding the Git source fails, restore the previous source with codex plugin marketplace add /path/to/your/previous/folder; that folder is not deleted by source removal.

ZIP fallback

To use an extracted archive folder as a local marketplace instead, run codex plugin marketplace add . and the plugin add command above. A local source does not fetch updates from Git; migrate it before using the Git refresh command. Keep only one source named nabit-oauth.

Connection help

If the browser reports that 127.0.0.1 is unreachable after approval, check your client's terminal result first. A successful login message means the client already received the one-time OAuth callback; verify the required range with a live connection check (get_connection_status), and use the continuation helper if the current conversation retains an older grant. Never paste callback URLs, tokens, or passwords into chat. Do not use legacy connection.json files. Disable any older local Nabit plugin so only one Nabit entry is active.

Release details: https://nabit.ai/codex#updates

Ordinary verified Nabit accounts can sign in at https://nabit.ai/auth and authorize their own workspace. Connecting is free; using business tools, including inspecting products, requires an active workspace trial or subscription; recommendation matching uses available credits. Insufficient credits return HTTP 402 with the required/available amounts and https://nabit.ai/credits. The agent provides the link; the user completes any recharge themselves. Reading an already settled batch does not charge again.

0.5.5 changes

Retired source-research tools have been removed (31 tools remain). New browser connections explicitly request workspace access. Existing product grants keep their original scope and must reconnect to use current matching, credits or trends. The compatibility recommendation reader now uses the current matching batch. A missing trial or subscription is reported as plan_required on an authenticated connection; it is not a failed login.
