Understand GAIP without a human briefing.

Connect a client

First call in 30 seconds

MCP endpoint: https://www.gaipagents.com/mcp (streamable HTTP, no account or key). A2A endpoint: https://www.gaipagents.com/a2a/agentverse · A2A Agent Card.

First call: gaip_check

Paste this into a terminal. It checks a public MCP server and runs as-is; then put your own agent's URL in 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":2,"method":"tools/call","params":{"name":"gaip_check","arguments":{"url":"https://mcp.deepwiki.com/mcp"}}}'

Plain HTTPS

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

Free, read-only, no account or key. The first call runs as-is against a public MCP server; then put the URL of the agent you want to check in "url". ChatGPT, the OpenAI Agents SDK, LangChain and more: client quickstart. Machine-readable: listing kit (client_config).

MCP tools

Five tools on /mcp

Start with gaip_check and a url; if a call failed, gaip_diagnose. Every question GAIP answers is on the map.

tools/list on https://www.gaipagents.com/mcp returns these five. Every other GAIP tool stays callable there by name; the full catalogue is listed at https://www.gaipagents.com/mcp/all and each specialist lists its own tools.

• gaip_check: Check an AI agent, MCP server or API. does this agent, MCP server or API work, is it reachable, has it changed? (url).
• gaip_diagnose: Why did my agent or API call fail?. paste a failing agent, MCP or API error: the cause, retry timing and the exact fix (error, http_status, url).
• gaip_watch: Watch an agent or MCP server for changes. follow an agent or MCP server for changes: feed links, optional webhook watch (url, webhook_url).
• gaip_verify: Verify a delivery or citations. did a service deliver what was promised; do cited pages contain the quoted text (url + result | citations); claims are compared with observations you supply.
• second_look_check: Second Look: check before you buy. before buying what an AI suggested: does the shop's own page show that price and stock now, with a signed receipt (url, claim).

The data record

Before you connect: has it changed?

GAIP keeps a dated, hash-chained record of what public MCP servers and A2A agents declared. Two free tools use it. Has this MCP server changed since? Ask before your agent connects: GAIP says when it began recording the server, what changed since your date, and whether your tool list matches what it last saw (/v1/free/observatory/changed-since, MCP tool gaip_tools_changed_since; it sends nothing to the server).

curl "https://www.gaipagents.com/v1/free/observatory/changed-since?url=https://huggingface.co/mcp&since=2026-10-01"

Save this agent now. GAIP reads what a public MCP server or agent card declares, keeps a dated, hashed record of it, and from then on revisits it about once a day (POST /v1/free/observatory/capture, MCP tool gaip_observatory_capture).

curl -X POST https://www.gaipagents.com/v1/free/observatory/capture -H 'Content-Type: application/json' -d '{"url":"https://mcp.deepwiki.com/mcp"}'

Facts at a stated time, not an assessment of any party. What GAIP records and for how long · Daily anchors · Corrections and opt-out

May my agent fetch this? Record extracts and a test range

May my agent fetch this? gaip_check_permission (on the integration-protocol agent; or gaip_check with agent) reads a site's robots.txt, Content-Signal and AI-preference lines, RSL licence links, tdmrep.json and llms.txt once and answers ALLOWED, DISALLOWED, NO_RULE or UNKNOWN for your agent's user-agent token, with the rule quoted, the time and a signature. A reading of the site's published files at the stated time; not legal advice or a licence. Try it: {"url":"https://www.gaipagents.com/test-range","agent":"GPTBot"}

An extract of GAIP's record. gaip_record_extract (on Witness) returns what GAIP recorded about an agent card, MCP endpoint or shop page, each entry with its chain position, hash and covering daily anchor, signed. Free preview; it shows what GAIP recorded and when, not that it is true. Example.

Test range. /test-range is synthetic: a demo shop page whose sources disagree and an MCP server that fails on request, to try GAIP's tools against. It is never counted as use.
