Is policylayer-registry live?

No — it has stopped answering the hub's checks (checked 3h ago). It answered 99% of checks over the last 30 days.

Is policylayer-registry free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does policylayer-registry have?

5 tools: check_mcp_server, check_mcp_stack, check_tool, search_registry, get_change_events.

Is policylayer-registry safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_change_events reads auth-required 18h ago

  The registry change feed: tool-surface drift, auth-posture flips, impostor flags, version bumps — every event the freshness watchers emit, id-cursored so a consumer resumes exactly where it stopped. Requires a Registry Licence key (Authorization: Bearer plr_...); self-serve at https://policylayer.com/registry/pricing.

• check_mcp_server reads unknown 18h ago

  Check an MCP server against the PolicyLayer registry BEFORE installing or allowing it. Accepts a registry slug, an npm package name (scoped or not), a remote server URL (https://…), or a server name. Returns the full published record: identity verification with its evidence, risk grade, auth posture, freshness, and the tool surface listed riskiest-first. A server the registry does not know is queued for scanning by this very call — check back shortly.

• check_mcp_stack reads unknown 18h ago

  Check a whole MCP stack against the PolicyLayer registry in one call — up to 25 servers, each given as candidate identifiers (npm package name, registry slug, or remote URL) tried in order until one resolves. Returns the published record for every hit — plus a deterministic verdict (attention signals and a suggested action) — and the lookup status for every miss; counts, grades and flagged tools come from the published records only. Costs one rate-limit unit per server.

• check_tool reads unknown 32h ago

  One tool's full risk classification on a published MCP server: category, severity, risk analysis and evidence, OWASP classes, parameter schema and the recommended policy default. Use when deciding whether to allow a specific tool call, e.g. "should execute_sql on this server be permitted?"

• search_registry reads unknown 32h ago

  Search the PolicyLayer registry of published MCP servers by name, slug or package substring. Returns candidate matches with risk grade, identity confidence (verified / unverified / mismatch — mismatch means it claims to be an official server with no verifiable link to the brand) and tool count — follow up with check_mcp_server on the match you meant.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
