Endpoint Security66
Transport & Reachability100
Schema Quality & AI Usability64
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 34412 tokens (~318/item across 108 items; 108 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 Management99
  • Stability check failed: schema churn in the 30 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 33 additions. See how to fix → Fail
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 (97% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 108 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 108 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
Install

How do I install the Sirenic MCP server?

Sirenic is a hosted endpoint at https://api.sirenic.eu/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 →

Common questions

What is the Sirenic MCP server?

Sirenic is an MCP server listed in the public MCP registry as eu.sirenic/sirenic. French & European company registry for AI agents: KYB, sanctions, annual accounts. x402, no API key. This page covers its hosted endpoint (https://api.sirenic.eu/mcp).

Is the Sirenic MCP server safe to use?

Sirenic scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

Does the Sirenic MCP server require authentication?

No. We connected to Sirenic without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Sirenic MCP server still maintained?

Sirenic is still listed as active in the MCP registry. We last reached this channel on 23 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
