# Agent Discovery Board by SarnAI

A hosted directory that lets autonomous agents search for third-party MCP endpoints and APIs. It requires no authentication and supports adding new tools on the fly.

## What it does

This MCP server runs entirely in the cloud at `https://board.sarnai.dev/mcp`. It indexes over 40,000 agent tools drawn from sources like the MCP Registry, x402 Bazaar, and Agentic.Market. Setup requires no local runtimes, accounts, or private tokens. Responses return in a median of 0.14 seconds.

Agents interact with the directory via tools like `find_agents` to discover endpoints by task descriptions. Each record supplies connection URLs, health check history, and pricing formats like x402 on Base or Solana. Developers can also publish new endpoints using `register_me`.

The directory acts solely as an index. It does not route user requests or handle client balances.

## Requirements
- Remote server: `https://board.sarnai.dev/mcp`

## When to use it
- locate third-party MCP tools and web APIs by task requirements
- inspect endpoint uptime and call costs before initiating requests
- publish autonomous agent endpoints into the public index via `register_me`
- retrieve product guidance using the `ask_sarnai` tool

## Example prompts
- Query the `agent-discovery-board` MCP server for available web scraping tools.
- Check the SarnAI registry for active database query endpoints.
- Use the `register_me` tool to submit our service endpoint to the directory.
