Now part of GAIP Check and GAIP Watch: compares supplier snapshots and watches for change.
Maintain this server? Claim it
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Use this when asked what changed between two versions of an agent card, MCP server description or OpenAPI document ("did this API break?"). Pass `prior` and `current`. Returns each change as BREAKING / NON_BREAKING / INFO with migration notes and a receipt. Free, no account; records a GAIP receipt only. Inputs must be public and non-personal.
The earlier version: agent card, MCP server description, OpenAPI document or snapshot.
The later version, same kind as `prior`.
Counterparty protocol. Inferred from metadata when omitted, otherwise MCP.
Optional: true marks a test call.
Optional: your own id to group related calls.
Optional: short name of the task, e.g. weather_forecast.
Name or URL of the agent/service. Optional.
Optional: the continuity_handle from an earlier GAIP result; links this call to your earlier ones.
PUBLIC (default) or NON_PERSONAL_PUBLIC. Never send personal data.
Optional: your operator id (recorded as a claim, not verified).
This tool isn't marked read-only, so it may change something on the server or in an account you connected.

}Use this when a supplier agent or API you depend on started failing ("did something change on their side?"). Pass its `supplier_url` and the `failure`. Returns the diagnosis plus changes GAIP observed around then (correlated in time, not causation), with receipts. Free, read-only, no account; inputs must be public and non-personal.
| Argument | Type | Description |
|---|---|---|
| card | object | Optional supplier card / server description you integrated against. |
| failure | object | {code, detail?, http_status?} as for gaip_diagnose_integration_failure. |
| failures | array | Optional: several failures, each {code, detail}. |
| protocol | string | Omit to infer it from card, transport or the supplier URL path (else UNKNOWN). |
| transport | string | Optional transport you used (e.g. streamable-http, sse, GRPC). |
| task_class | string | Optional: short name of the task, e.g. weather_forecast. |
| supplier_url* | string | Public https URL of the supplier's agent card, MCP server or API. |
| lookback_days |
Use this when asked what changed on a watched agent or service. Pass your `continuity_handle` and optionally a `watch_id`. Returns recent change events: verdict before and after, a change summary, the receipt and webhook delivery status. Free, read-only, no account; inputs must be public and non-personal.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Optional: maximum events to return. |
| watch_id | string | The watch_id returned by gaip_watch_register. |
| continuity_handle* | object | The continuity_handle from an earlier GAIP result; proves you own these watches. |

}Use this when asked which agents or services you are watching. Pass your `continuity_handle`. Returns each watch's kind, target, last verdict, last and next check and webhook endpoint (never the secret). Free, read-only, no account; inputs must be public and non-personal.
| Argument | Type | Description |

},
"additionalProperties": false
}Use this when asked to keep an eye on an agent or MCP server ("tell me if it changes or goes down"). Pass the `continuity_handle` from any GAIP result, `kind` and `target_url`. GAIP re-checks every 24 hours (3 free watches), receipts each change and can call your webhook. Free, no account; records a GAIP receipt only. Inputs must be public and non-personal.
| Argument | Type | Description |
|---|---|---|
| sla | object | DELIVERY_SLA only: service-level terms checked on every observation, any of min_uptime_pct, max_latency_ms, required_fields (JSON key paths), freshness_field + max_age_seconds; optional uptime_window_hours, min_observations. Results go only to you. |
| kind* | string | AGENT_READINESS (agent URL), SUPPLIER_CARD (published card), DELIVERY_TERMS (terms_id) or DELIVERY_SLA (terms_id plus sla terms). |
| terms_id | string | DELIVERY_TERMS or DELIVERY_SLA: terms_id from witness_register_terms. |
| target_url | string | Public https URL (AGENT_READINESS, SUPPLIER_CARD). No query string. |
| webhook_url | string | Optional: your own public https endpoint for signed change events. |
| interval_hours | integer | Hours between checks: 24 minimum on the free tier; 1 for DELIVERY_SLA. |
| continuity_handle* | object |
Use this when asked to stop watching an agent or service. Pass your `continuity_handle` and the `watch_id`. Its stored events are deleted; retained receipts stay verifiable. Free, no account; records a GAIP receipt only. Inputs must be public and non-personal.
| Argument | Type | Description |
|---|---|---|
| watch_id* | string | The watch_id returned by gaip_watch_register. |
| continuity_handle* | object | The continuity_handle from an earlier GAIP result; proves you own these watches. |
