Also listed as glama/claracarspt/clara-carros-mcp-server
As of 2026-10-17 17:33 UTC, the Claracarspt MCP server is up with a Glimind reliability score of 92/100 (grade A). Over the last 30 days it answered 100% of Glimind's liveness checks. It had 23 outages in 90 days, with a median recovery of 2 minutes.
Used & imported cars in Portugal: search stock, ISV/IUC tax calc, resale value, contact.

Third-party server, listed as discovered. Review its source before installing.
11 of 11 tool(s) carry no readOnlyHint/destructiveHint annotations.
Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones.
Handshake + tools/list takes ~1,654 ms.
Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.
No tool declares an outputSchema.
Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably.
In the last 30 days: 0 tool(s) removed and 5 schema change(s).
Add new tools or optional parameters instead of renaming or removing; deprecate first (say so in the description) and remove later. Agents cache tool contracts.
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. All of them as JSON: /v1/readiness/mcp-registry%2Fio.github.claracarspt%2Fmcp/fixes

Glimind scanned all 11 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
