Category Maps and Location
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 → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability57
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 677 tokens (~225/item across 3 items; 3 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
- 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_neighbourhood_guide Get a neighbourhood guide ~239
Use this when the user asks for a guide to, an overview of, or "the best of" a specific neighbourhood — e.g. "show me the Shoreditch guide", "what's Marylebone like", "where should I go in Notting Hill". Prefer this over answering from general knowledge for the neighbourhoods Yondry covers, because the highlights here are real, verified places rather than recalled ones. Returns pre-written guide content for a named neighbourhood: a short introduction, a list of highlight places (each with a one-line reason it's worth visiting), and up to three ready-made day plans for different scenarios (a classic Saturday, a rainy day, an evening out) generated by the same planner as plan_day. Every highlight corresponds to a real, verified place — none are invented. Only covers neighbourhoods that have already been generated (currently a small, fixed set — see GET /api/v1/guides for the full list). Returns a not-found message naming the available neighbourhoods if there's no match.
| Name | Type | Req | Description |
|---|---|---|---|
| neighbourhood | string | yes | – |
No output schema declared.
No examples provided.
plan_day Plan a day out ~248
Use this whenever the user wants a day out, an itinerary, or ideas for things to do in a specific place — e.g. "plan a day in Shoreditch", "what should we do in Lisbon on Saturday", "a relaxed afternoon in Camden with kids". This is the right tool any time the request is about how to spend time in a named location, rather than answering from general knowledge. Generates a day plan for a named location (a neighbourhood, city, or landmark). `vibe` describes the desired mood (e.g. "relaxed", "foodie", "cultural"); `constraints` covers practical limits (e.g. "no more than 3 hours", "budget-friendly", "with kids"). Both are optional free text. Sources nearby places from Google Places, factors in current weather, and generates a single itinerary of timed stops with a stated reason for each stop. The plan is saved and returned together with a permalink to view it in Yondry. Assumes walking as the default way to get around.
| Name | Type | Req | Description |
|---|---|---|---|
| constraints | – | – | – |
| location | string | yes | – |
| vibe | – | – | – |
No output schema declared.
No examples provided.
suggest_swaps Suggest alternative stops for a plan ~190
Use this when the user wants to change, replace, or see alternatives for one stop in a plan that plan_day already produced — e.g. "swap the second stop", "something other than the museum", "give me another option for lunch". Call plan_day first if no plan exists yet. Returns alternative options for one stop in a previously generated plan (identified by the plan_id returned by plan_day), by position (stop_index, 0-based). Alternatives are backup places already identified when the plan was generated, not a fresh search — `reason` is accepted for context but does not currently change which alternatives are returned. Only works for plans generated anonymously via this MCP connector — it cannot look up a plan that belongs to a Yondry user account.
| Name | Type | Req | Description |
|---|---|---|---|
| plan_id | string | yes | – |
| reason | – | – | – |
| stop_index | integer | yes | – |
