Freelancer MCP Server

Freelancer MCP Server

An MCP server that connects Claude (Desktop, Code, or any MCP-compatible client) directly to Freelancer.com. Search and bid on projects, read and reply to client messages, review your track record, and manage skills/specialty profiles — all from a chat.

Supports multiple Freelancer accounts in one server (e.g. your own account plus one or more clients' accounts you manage), switchable per tool call.

This project is 100% self-contained: it talks only to freelancer.com's public API using whatever access token(s) you provide. No other data source, project, or third-party service is involved.

Get your access token (do this first)

1. Log in to Freelancer.com
2. Go to accounts.freelancer.com/settings/develop
3. Under Application Dashboard, click Generate Token
4. Copy the token shown under Access Token

That token is all this server needs — no password, no app review, no OAuth redirect flow. Repeat this for each additional Freelancer account you want connected (see Multiple accounts).

What you can ask Claude

Every tool accepts an optional account argument to pick which connected Freelancer account it should act on/as (see Multiple accounts).

Analyzing past projects & winning strategy

There's no single "analyze my strategy" button — instead, Claude does the analysis itself over the raw data this server exposes. This keeps the server a thin, honest API wrapper instead of a black box. Ask things like:

"Pull my awarded bids and my rejected bids, then compare amount, delivery time, and proposal length/style to figure out what's working."

"Look at my completed projects and tell me which skills show up most often."

"Compare my bid on project X to the other bids on it — am I priced competitively?"

Claude will chain freelancer_my_bids (status awarded vs rejected), freelancer_my_projects (status complete), and freelancer_get_project_bids to gather the data, then reason over it directly in the conversation.

Chat links and thread IDs

freelancer_get_messages and freelancer_send_message accept either a plain numeric thread ID or a pasted Freelancer chat/message link — the server extracts the ID either way.

Setup

The package is published on npm as freelancer-mcp-server — no clone, no build, npx fetches and runs it on demand.

Claude Code (CLI)

claude mcp add freelancer --env FREELANCER_OAUTH_TOKEN=your_token_here -- npx -y freelancer-mcp-server

Or just ask Claude Code directly, in plain English, once you have your token:

"Add the freelancer-mcp-server MCP server using npx, with my Freelancer access token set as FREELANCER_OAUTH_TOKEN"

Claude Code can run the claude mcp add command itself — you don't have to type it.

Claude Desktop

Open your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this block inside "mcpServers" (create the file if it doesn't exist):

{
  "mcpServers": {
    "freelancer": {
      "command": "npx",
      "args": ["-y", "freelancer-mcp-server"],
      "env": {
        "FREELANCER_OAUTH_TOKEN": "your_token_here"
      }
    }
  }
}

Restart Claude Desktop — you should see a 🔌 indicating the server connected.

Multiple accounts

To connect more than one Freelancer account (your own plus, say, two clients'), use FREELANCER_ACCOUNTS instead of FREELANCER_OAUTH_TOKEN — a JSON object mapping a label you choose to each token:

{
  "mcpServers": {
    "freelancer": {
      "command": "npx",
      "args": ["-y", "freelancer-mcp-server"],
      "env": {
        "FREELANCER_ACCOUNTS": "{\"main\":\"token1\",\"client_acme\":\"token2\"}"
      }
    }
  }
}

Or via claude mcp add:

claude mcp add freelancer --env FREELANCER_ACCOUNTS='{"main":"token1","client_acme":"token2"}' -- npx -y freelancer-mcp-server

The first account listed becomes the default (used when a tool call omits account). Ask Claude "which Freelancer accounts are connected?" to confirm, then say e.g. "using the client_acme account, show me the latest projects" to target a specific one. Tokens are never logged, echoed back, or written anywhere by this server — they only ever go into the outgoing freelancer-oauth-v1 header.

Running from source (contributing)

git clone https://github.com/godesigntech/freelancer-mcp-server.git
cd freelancer-mcp-server
npm install
npm run build
claude mcp add freelancer --env FREELANCER_OAUTH_TOKEN=your_token_here -- node /FULL/PATH/TO/freelancer-mcp-server/dist/index.js

Testing

Ask Claude:

"Show my Freelancer profile"

If it responds with your username and stats, you're set.

Profile editing — what the Freelancer API actually allows

The Freelancer.com public REST API is read-mostly for profiles. After probing the live API, here's the real boundary:

Editable:

• ✅ Skills/jobs — add, remove, or replace the skills on an account (/users/0.1/self/jobs). Freelancer caps the total number of skills per account.
• ✅ Specialty profiles — create/update focused sub-profiles (/users/0.1/profiles): tagline, hourly_rate, description, skills. Caveats: the API has no endpoint to list your own profile IDs (you must already know them), and some account types (e.g. certain corporate accounts) cannot create new ones.

NOT possible via the public API (web-UI only):

• ❌ Main account bio/tagline/hourly rate shown on your public page
• ❌ Profile photo / avatar
• ❌ Experience, education, publications, references, certifications
• ❌ Portfolio (read-only via API)

Security notes

• Tokens live only in your local MCP client config (or .env for npm run dev) — never committed, never sent anywhere but Freelancer's own API.
• The server runs entirely on your machine; no telemetry, no third-party calls.
• Destructive/real-world actions (place_bid, send_message, skill/profile edits) always surface for your review before they execute, since Claude shows tool calls before running them.
• This repo contains no data from, and no dependency on, any other project — it's a clean, standalone Freelancer.com integration.

Troubleshooting

"no Freelancer accounts configured" → Set FREELANCER_OAUTH_TOKEN or FREELANCER_ACCOUNTS in your MCP client config.

401 Unauthorized → Token expired or wrong. Generate a fresh one at https://accounts.freelancer.com/settings/develop

"Unknown account "x"" → Run freelancer_list_accounts to see the exact labels configured, then use one of those.

Tool not appearing in Claude → If using npx, confirm Node.js 18+ is installed and npx -y freelancer-mcp-server runs without error from a terminal. If running from source, confirm the path in your config is the absolute path to dist/index.js, and that npm run build succeeded.

Contributing

Issues and PRs welcome. Keep changes scoped to the Freelancer.com API surface — this project intentionally stays a single-purpose, dependency-light MCP server.
