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 Security57
Transport & Reachability100
Schema Quality & AI Usability76
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 5686 tokens (~135/item across 42 items; 42 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 Management90
  • Stability observed for 27 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
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety95
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 4 of 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "execute_sql" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Partial
  • An AI judge read all 43 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass
Install

How do I install the Compabase MCP server?

Compabase is a hosted endpoint at https://compabase.com/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.

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 →

search_companies ~924

Search and filter Polish KRS companies (spółki). Compabase also holds the full CEIDG/JDG register; this tool does not browse JDG — those without a public contact email are hidden because of RODO. Default `fields=summary` returns a compact row (name, NIP, KRS, location, PKD, latest financials, email/phone/website) — small enough for MCP clients. `fields=contacts_only` is name/NIP/KRS/city/email/phone/website only. `fields=full` returns every company_search column plus contacts and may exceed client size limits. Use for rankings, sector filters, city/county/region browsing, name search, or NIP/KRS lookup. When a PKD is mostly JDG, a sparse result includes a `hint` (full CEIDG is in the database; listing is RODO-gated). Do not call export_companies just to get a handful of emails or phones.
