Unauthenticated OAuth2 callback collector for Tollbooth MCP services
Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 687 tokens (~171/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 19 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.
- 17 Aug 26 0
- Tool “store_code” rewrote its description, which is the text the model reads security
- Schema quality: 150 → 171 ▼ functional

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
collector_status ~21
Health check — shows the number of pending authorization codes and TTL.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
retrieve_code ~106
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. Args: state: The state token (patron npub) used during authorization. Returns: Dict with ``code`` (encrypted) on success, or ``error`` if not found.
| Name | Type | Req | Description |
|---|---|---|---|
| state | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
service_status ~172
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.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
store_code ~185
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. Args: code: The authorization code from the OAuth provider. state: The packed state (``patron_npub.operator_npub``). Returns: Dict with ``success`` key and a message.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | – |
| state | string | yes | – |
Structured output declared, but exposes no named fields.
