Changes things 1Claude Code: ask
  • store_codeStore a sealed OAuth2 authorization code.No findings

    Why it is in this group

    • The name "store_code" says "store": a word for a change.
    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    Store a sealed OAuth2 authorization code. Called by the serverless callback function after the browser redirect. The ``state`` carries BOTH the patron npub (the lookup/retrieve key) and the operator npub (the PUBLIC key the code is sealed to) — see the SDK's ``pack_oauth_state``. The code is sealed with NIP-44 to the operator so only that operator's nsec can open it; the Neon row is keyed by the patron npub, so retrieval (``retrieve_code(state=patron_npub)``) is unchanged.
Only reads 3Claude Code: allow
  • collector_statusHealth check — shows the number of pending authorization codes and TTL.No findings

    Why it is in this group

    • The name "collector_status" says "status": a word for reading.
    Description, as the server wrote it
    Health check — shows the number of pending authorization codes and TTL.
  • retrieve_codeRetrieve a stored authorization code (one-time read, auto-deleted).No findings

    Why it is in this group

    • The name "retrieve_code" says "retrieve": a word for reading.
    Description, as the server wrote it
    Retrieve a stored authorization code (one-time read, auto-deleted). Called by the originating MCP server to pick up the code after the user has authorized in the browser. Returns the encrypted code which the caller decrypts using the same state token.
  • service_statusReport the running build so a redeploy can be verified.No findings

    Why it is in this group

    • The name "service_status" says "status": a word for reading.
    Description, as the server wrote it
    Report the running build so a redeploy can be verified. Free. Delegates to the SDK's canonical ``build_service_status`` — the single source of the service_status payload shape — so this collector reports the same envelope as every other DPYC service. The load-bearing field is ``build_info.fastmcp_cloud_git_commit_sha``: the commit Horizon actually deployed. The post-merge deploy-verify probe reads it to confirm the live service redeployed the merged sha; with no ``service_status`` tool to probe, that sha reads as ``<none>`` and an otherwise-healthy deploy is flagged as "did not land". The vault/courier/operator fields are ``False``/empty by construction — this is an unauthenticated community utility with no operator runtime.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__tollbooth-oauth2-collector__retrieve_code",
      "mcp__tollbooth-oauth2-collector__collector_status",
      "mcp__tollbooth-oauth2-collector__service_status"
    ],
    "ask": [
      "mcp__tollbooth-oauth2-collector__store_code"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as tollbooth-oauth2-collector. Review it before you use it.
