How do I install the fabler x402 tools mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `X402_BUYER_PRIVATE_KEY`, `X402_BASE_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Fabler X402 Tools MCP Server?

The short version

Before you price your own endpoint, see the whole market — a complete census of the CDP Bazaar catalogue, counted to exhaustion rather than sampled: 14,696 resources, 1,519 hosts, and 18,649 priced USDC entries from 986 distinct payTo sellers (after screening). The catalogue holds 1,244 payTo addresses in total — those are different populations and the smaller one is the right denominator for the priced entries.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
