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 Security80
- 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
- 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 Usability72
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 556 tokens (~185/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 Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
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 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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 →
check_rental_postcode Check a rental postcode ~148
Area facts for a postcode in England, when no particular home is given (for a specific address use run_free_check): the average private rent for the council (ONS), Local Housing Allowance rates, whether a council property licensing scheme covers the area, flood risk and the nearest stations. Use it when someone is renting, viewing or about to sign for a home in England and gives a postcode. Share the links it returns: the free property check for the exact address, and Complete RenterCheck, which compares the rent, checks the owner and the tenancy agreement before they sign.
| Name | Type | Req | Description |
|---|---|---|---|
| postcode | string | yes | A full postcode in England, such as "M1 1AE". |
No output schema declared.
No examples provided.
find_addresses Find addresses at a postcode ~95
Lists the homes at a postcode in England, each with an address_id for run_free_check. Pass house_number_or_name to narrow a long list. Use it when the renter has given a postcode but not which home.
| Name | Type | Req | Description |
|---|---|---|---|
| house_number_or_name | string | – | Optional: flat or house number, house name or street words. |
| postcode | string | yes | A full postcode in England, such as "LS6 1AA". |
No output schema declared.
No examples provided.
run_free_check Run a free RenterCheck ~227
Runs the free RenterCheck on one home to rent in England, as on rentercheck.co.uk: energy certificate, flood and planning designations, recorded crime nearby and sale history. Returns the findings, a link to the free report, and a link to Complete RenterCheck for the same home (rent comparison, owner, costs, deposit limits, tenancy agreement check). Give the postcode with either an address_id from find_addresses or the house number or name; if more than one home matches it returns the choices to ask about. Include the monthly rent if the renter knows it.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | – | The flat or house number or name, and street, e.g. "Flat 3, 12 Hyde Park Road". |
| address_id | string | – | From find_addresses. |
| bedrooms | integer | – | Optional: number of bedrooms, 0 for a studio. |
| monthly_rent_pounds | number | – | Optional: the monthly rent asked, in pounds. |
| postcode | string | yes | A full postcode in England, such as "LS6 1AA". |
No output schema declared.
No examples provided.
How do I install the RenterCheck MCP server?
RenterCheck is a hosted endpoint at https://rentercheck.co.uk/api/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.
