GAIP — evidence on AI agents before and after you call them MCP server

GAIP Agents

Free, read-only evidence on AI agents and MCP servers: conformance, change, delivery, receipts.

GAIP checks the public declarations of AI agents and MCP servers, watches them for change, witnesses what a delegated call returned and keeps verifiable receipts. Calls are free and need no account or API key; public or non-personal data only.

• Website: https://www.gaipagents.com
• MCP (Streamable HTTP, no auth): https://www.gaipagents.com/mcp
• A2A agent card: https://www.gaipagents.com/.well-known/agent-card.json
• OpenAPI 3.1: https://www.gaipagents.com/openapi.json
• Agent-readable guide: https://www.gaipagents.com/llms.txt
• Official MCP Registry: io.github.tjcgraham-rgb/gaip-broker plus eleven specialist records (three listed faces below)

This repository holds GAIP's public face only: registry records, the listing kit, a small Python client, a GitHub Action, examples and logos. The service itself runs at www.gaipagents.com.

Three public faces

Still callable at their own endpoints with the same tools, no longer listed separately (founder decision, 1 Oct 2026): buyer-assurance, procurement-verify, trust-assurance and outcome-value (part of Witness); supplier-watch and integration-repair (part of the developer checks); opportunity-broker and art-intelligence (unlisted).

Each specialist has its own MCP endpoint (https://www.gaipagents.com/mcp/agents/) and A2A card (https://www.gaipagents.com/agents//.well-known/agent-card.json).

Try it

First call over MCP: check a public MCP server (runs as-is; then use your own agent's URL):

curl -s https://www.gaipagents.com/mcp \
  -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"gaip_check","arguments":{"url":"https://mcp.deepwiki.com/mcp"}}}'

What GAIP has recorded about a server (REST):

curl -s 'https://www.gaipagents.com/v1/free/observatory/lookup?url=https://mcp.deepwiki.com/mcp'

A2A, plain text works:

curl -s https://www.gaipagents.com/a2a/agentverse -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"kind":"message","role":"user","messageId":"m1","parts":[{"kind":"text","text":"check https://mcp.deepwiki.com/mcp"}]}}}'

Add GAIP to an MCP client:

{ "mcpServers": { "gaip": { "type": "http", "url": "https://www.gaipagents.com/mcp" } } }

Use it in CI (GitHub Action)

Check your agent card, MCP server or OpenAPI document on every push, free and with no key:

- uses: tjcgraham-rgb/gaip-agents@v1
  with:
    agent-url: https://your-agent.example/.well-known/agent-card.json
    fail-on-error: "true"

Outputs: verdict (READY, FIXESNEEDED, UNREACHABLE or NOTCHECKED), receipt-id, error-count, warning-count.
