Authorized domain actions. Supply the selected action's full parameters in input; etag and idempotencyKey are transport controls. Linked source access is independent. Literal bounded uploads are supported; local filesystem collection/watch requires CLI. Agent reports cannot create human Decisions. Use Interaction tools for human requests and immutable receipts.

## Connect and discover

Connect an authenticated [MCP client](/docs/build/mcp). Call `tools/list` to confirm this tool is available to the current credential. Provider, workspace, and agent grants remain separate access checks.

## Input fields

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `action` | `"attach"` · `"requirements_create"` · `"claims_create"` · `"evidence_get"` · `"list"` · `"evidence_update"` · `"evidence_archive"` · `"requirement_get"` · `"requirements_list"` · `"requirement_update"` · `"requirement_archive"` · `"claim_get"` · `"claims_list"` · `"claim_update"` · `"claim_archive"` · `"history"` · `"link"` · `"report"` · `"export"` · `"import"` · `"verification_request"` · `"verification_get"` · `"verification_cancel"` · `"verification_retry"` · `"verification_artifact"` | Yes | Implemented domain action. |
| `input` | object | Yes | Exact action input including path identities. |
| `etag` | string | No | Exact resource ETag for conditional writes. Maximum length: 1024. |
| `idempotencyKey` | string | No | Reuse only for the identical operation intent. Maximum length: 200. |

## Call the tool

Send a `tools/call` request with `name: "project_evidence"` and an `arguments` object containing the required fields above. Choose an advertised action, then supply the fields required by that action. Do not treat a successful request as human approval or verified execution unless the returned contract explicitly records that fact.

## Errors and recovery

Read the returned error and permission requirements. Refresh stale revisions before conditional writes, retain idempotency keys only for exact retries, and reconnect when a credential has expired.
