What replicate.com declares an agent can do
Measured 2026-10-04 18:19 UTC from the declarations the site publishes (record s6fn384i4m). Each capability is shown as declared, under the policy class that decides whether anything may call it, beside what a call observed.
Declared versus observed
| Capability | Policy class | Declared | Observed |
|---|---|---|---|
| server mcp · https://mcp.replicate.com/sse | Metadata never called automatically | a server declaration; its tools are listed only by the server itself (tools/list), which is not called auth: unknown | not attempted on another origin (mcp.replicate.com): only the scanned origin is called |
| server mcp · https://mcp.replicate.com/sse | Metadata never called automatically | a server declaration; its tools are listed only by the server itself (tools/list), which is not called auth: unknown | not attempted on another origin (mcp.replicate.com): only the scanned origin is called |
| replicate agent_skill · https://raw.githubusercontent.com/replicate/skills/8c871d6530d825178b2b13125c00ffd409edbd98/skills/replicate/SKILL.md | Metadata never called automatically | an instruction file an agent reads; not an operation auth: none | not attempted on another origin (raw.githubusercontent.com): only the scanned origin is called |
Where the declaration and the call disagree
None: every capability that was called answered as declared.
Signed certificate
This page’s rows, signed by the observer’s Ed25519 key: every capability’s id, endpoint, safety class, policy class and observed state, the declaration hashes and the record’s sealed manifest. The certificate is derived from the record alone, so the same record always yields the same id.

The certificate as JSON · verify it now · the key directory · machine-readability certificate
To verify it yourself: SHA-256 the certificate object as canonical JSON (keys sorted, no whitespace); the hex digest must equal certificate_sha256 and the id; then check the Ed25519 signature over "crawlcheck-capability-certificate-v1\n" followed by that hex digest, with the key in the directory whose RFC 7638 thumbprint is the kid.
Policy classes
| Policy class | Called automatically? | Rule |
|---|---|---|
| Public read-only public_read_only | yes, to verify | May be called without credentials. CrawlCheck calls it only to check the declaration: GET with no input, on the scanned origin. |
| Authenticated read-only authenticated_read_only | never | Never called by CrawlCheck. An agent needs the user's own credentials and consent. |
| Reversible write reversible_write | never | Never invoked automatically. Needs the owner's written authorisation and a test account. |
| Irreversible write irreversible_write | never | Never invoked automatically. Deletes or changes something that cannot be undone. |
| Financial financial | never | Never invoked automatically. Moves money or creates a charge. |
| External communication external_communication | never | Never invoked automatically. Sends a message, email or notification to someone. |
| Identity and accounts identity | never | Never invoked automatically. Creates, signs in to or changes an account or credential. |
| Unknown unknown | never | Never invoked. Its effect cannot be read from the declaration, so it is treated as the riskiest case. |
| Metadata metadata | never | Nothing to invoke: a listing, a server card or a skill file, not an operation. |
