TapTools API MCP

A Python-based Model Context Protocol (MCP) server that provides access to the TapTools API, enabling Large Language Models (LLMs) (like Claude or GPT) to fetch Cardano-related data (tokens, NFTs, market info, etc.). This server standardizes TapTools API operations into MCP "tools," allowing easy integration into AI workflows.

Features

• Async Implementation: Uses modern Python async patterns and httpx for non-blocking IO.
• Secure Authentication: Reads TAPTOOLS_API_KEY from environment variables or .env file.
• MCP-Ready: Exposes TapTools functionality as "tools" accessible by any MCP-compliant client.
• Token Operations: Pricing, top tokens, market cap data, volume stats, and more.
• NFT Operations: NFT collection stats, trades, listings, distribution, etc.
• Market Data: Aggregated stats on volume, addresses, holders, and more.
• Integration & Onchain: Access to onchain data, block info, events, DEX pairs, etc.
• Wallet Data: Portfolio positions, token/NFT holdings, transaction history, trades.

Quick Start

1. Clone the repository:
   git clone https://github.com/yourusername/taptools-api-mcp.git cd taptools-api-mcp
2. Create and activate a virtual environment:
   python3 -m venv .venv source .venv/bin/activate # On Windows: .venv\Scripts\activate
3. Install dependencies:
   pip install -e .
4. Set up your TapTools API key:
   • Option A: Add to your .env file:
     TAPTOOLS_API_KEY=your-real-taptools-api-key
   • Option B: Set the environment variable:
     export TAPTOOLS_API_KEY="your-real-taptools-api-key"
5. Run the MCP server:
   python -m taptools_api_mcp
   By default, it will run on standard input/output (stdio) for MCP integration.
6. Test the connection (optional):
   python test_connection.py

Usage Example

If you have an MCP client (such as the mcp Python CLI tools), you can start the server and call any of the available tools:

Once inside the mcp cli, you can call tools like:

This will verify that your TapTools API key is valid and accessible.

Or, for example, to get token market cap info:

You should receive JSON data with the token’s market cap, price, supply, etc.

API Documentation: MCP Tools

Below is a list of available MCP tools, their parameters, and brief descriptions. These tools must be called with the correct JSON payloads. All JSON requests must match the Pydantic models found in src/taptools_api_mcp/models/.

  { "quote": "string" // optional, default "ADA" }
• Sample Usage:
  { "quote": "USD" }

8. get_integration_asset

• Description: Get asset details by ID (integration endpoint).
• Parameters (IntegrationAssetRequest):

(Additional endpoints for tokens, NFTs, onchain, etc. can be added in the same format if needed. See the src/taptools_api_mcp/models/ folder for more possible requests.)

Deployment

You can containerize or host this Python MCP server on services like AWS ECS, Azure Container Instances, or Google Cloud Run. Make sure to securely store your TAPTOOLS_API_KEY as a secret. For Docker-based deployment:

Note: The server listens on stdio by default, per the MCP spec. For advanced deployment or custom integration, you can adapt server.py to run with alternative transports (like sockets) if your environment requires it.
