It allows LLMs to interact with blockchain data across multiple chains including Ethereum, BSC, Polygon, Avalanche, and more.\n\n## Features\n\n- Complete wrapper for all Ankr Advanced API endpoints\n- NFT API: Get NFT metadata, holders, transfers, and ownership information\n- Query API: Access blockchain statistics, blocks, logs, and transaction data\n- Token API: Get token balances, prices, holders, and transfer history\n- Support for multiple blockchain networks\n\n## Installation\n\n```bash\n# Clone the repository\ngit clone https://github.com/tumf/web3-mcp.git\ncd web3-mcp\n\n# Install with uv\nuv pip install -e .\n```\n\n## Configuration\n\nSet the following environment variables:\n\n```bash\n# Required\nexport ANKR_ENDPOINT=\"your_ankr_rpc_endpoint\"\n\n# Optional but recommended for authenticated requests\nexport ANKR_PRIVATE_KEY=\"your_private_key\"\n```\n\n## Usage\n\n### Running the server\n\n```python\nfrom web3_mcp.server import init_server\n\n# Initialize MCP server\nmcp = init_server(\n    name=\"Ankr MCP\",\n    endpoint=\"your_ankr_endpoint\",  # Optional, defaults to ANKR_ENDPOINT env var\n    private_key=\"your_private_key\"  # Optional, defaults to ANKR_PRIVATE_KEY env var\n)\n\n# Run server\nmcp.run()\n```\n\n### Using with FastMCP CLI\n\n```bash\n# Set environment variables first\nexport ANKR_ENDPOINT=\"your_ankr_endpoint\"\nexport ANKR_PRIVATE_KEY=\"your_private_key\"\n\n# Run the server\npython -m web3_mcp\n```\n\n## API Categories\n\n### NFT API…","publisher":null,"homepage":null,"repository":null,"version":"0.1.5","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:web3-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","summary":"pypi","version":"pypi","description":"pypi"}},"derived":{"capabilities":[{"slug":"dev.version-control","name":"Version Control","confidence":1,"provenance":"derived"}],"categories":["dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"web3-mcp","registry":"pypi","observedAt":"2026-09-10T15:25:24.498Z","publishedAt":"2025-04-18T12:12:53.321684Z","latestVersion":"0.1.5"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"web3-mcp","url":"https://pypi.org/project/web3-mcp/","firstSeenAt":"2026-09-10T15:24:20.218Z","fetchedAt":"2026-09-10T15:24:20.218Z","normalizedAt":"2026-09-10T15:24:20.218Z"}]},"firstSeenAt":"2026-09-10T15:24:20.218Z","updatedAt":"2026-09-10T15:25:24.498Z"}
