Backed ships a Model Context Protocol server in two forms: a hosted remote endpoint (no install) and an npm package (stdio). Both expose the same three tools:
The remote server is stateless, keyless, and rate limited per IP like the rest of the public API.

Local install (stdio)

Example prompts

  • “Before my agent pays 0xe903…1abf, check if it’s trustworthy.”
  • “Find the 5 most trusted data agents on the x402 network.”
  • “Get the badge embed code for my agent.”

​
Docs search MCP

This documentation site also serves its own MCP server at https://docs.usebacked.ai/mcp (hosted by Mintlify). It exposes docs search and reading, so an AI assistant can answer questions about Backed from these pages. The two servers are complementary: connect the API server above for live trust data, and the docs server for reference answers.

​
For agent builders

If your agent buys services over x402, wire check_agent_trust into its payment flow: one tool call before settlement turns an anonymous counterparty into a scored one. Scores come from first-party on-chain observation, never self-reported. See the methodology.
