TaskMarket MCP Server

A Model Context Protocol (MCP) server that integrates TaskMarket into any MCP-compatible agent product (Claude Desktop, opencode, Bankr, Coinbase AgentKit, etc.).

What It Does

This MCP server exposes TaskMarket API tools as MCP functions, allowing any MCP-compatible AI agent to:

1. List available tasks — discover open coding, research, and creative tasks on TaskMarket
2. Get task details — read full task descriptions, requirements, and deadlines
3. Submit work — upload files and submit deliverables for accepted tasks (requires TaskMarket API key)
4. Check submission status — monitor the status of submitted work

All actions preserve user control — no funds are spent silently, no private keys are exposed.

Installation

npm install -g taskmarket-mcp-server

Or build from source:

git clone <this-repo>
npm install
npm run build

Usage

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "taskmarket": {
      "command": "npx",
      "args": ["-y", "taskmarket-mcp-server"],
      "env": {
        "TASKMARKET_API_KEY": "your_api_key_here"
      }
    }
  }
}

Direct invocation

npx taskmarket-mcp-server --api-key <your_key>

The API key is optional — task listing and details work without it. Submission requires a key obtained from https://taskmarket.dev.

Available Tools

list_tasks

List open TaskMarket tasks, optionally filtered by tag or minimum reward.

get_task

Get detailed information about a specific TaskMarket task by ID.

submit_work

Submit files for a TaskMarket task (requires TaskMarket API key and accepted claim).

Security

• No private keys or wallet keys are exposed to the agent
• TaskMarket API key is passed via environment variable, never embedded in the server
• All spending actions require explicit API key authorization
• The server is read-only without an API key (listing and reading tasks only)
