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 → Why this is hard to score →
Endpoint Security63
- 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability68
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1115 tokens (~223/item across 5 items; 5 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 Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 93% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 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
How do I install the FrankSpace Public MCP server?
FrankSpace Public MCP is a hosted endpoint at https://bqixfybgflusxwnvzjwu.supabase.co/functions/v1/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.

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 →
ai_search Natural-language workspace search ~112

search_workspaces Search FrankSpace workspaces ~159
Search live UK workspace listings on FrankSpace. Filter by location text (city, postcode, submarket), size band, and maximum monthly price (pence). For richer natural-language queries prefer `ai_search`.
| Name | Type | Req | Description |
|---|---|---|---|
| client_hint | string | – | Name of the calling agent (e.g. 'claude', 'chatgpt') for analytics. |

submit_feedback Report a problem with FrankSpace data or docs ~317
Report something wrong or missing in FrankSpace's agent-facing surface: a listing whose details look stale or incorrect, a gap that made a search impossible, an unclear or contradictory statement in llms.txt / skill.md, or a tool that behaved unexpectedly. Feedback is reviewed by the FrankSpace team. Do NOT use this to contact a property owner, register interest in a workspace, ask a question, or pass on anything a user expects a reply to — nobody replies to this channel. Enquiries and viewings go through the listing page at https://frankspace.co.uk/office/<id>, by the user, on the site. Send one clear report rather than several; describe what you observed and what you expected.
| Name | Type | Req | Description |
|---|---|---|---|
| client_hint | string | – | Name of the calling agent (e.g. 'claude', 'chatgpt') for analytics. |
| kind | string | – | data_error: a listing's details are wrong or stale. missing_data: a field or filter you needed does not exist. docs_unclear: llms.txt / skill.md is unclear, contradictory or incomplete. tool_problem:… |
| message | string | yes | What is wrong, in plain English. Include what you observed and what you expected. Do not include personal data about the user. |
| subject_url | string | – | The FrankSpace URL the report is about, if not a specific workspace. |
| workspace_id | string | – | UUID of the workspace the report is about, when it concerns one listing. |
