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
Transport & Reachability100
Schema Quality & AI Usability69
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 169415 tokens (~536/item across 316 items; 315 tools + 1 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 Management53
  • Stability observed for 16 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 (99% of tools); any adoption earns full credit.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "consensus_from_traces" implies "merge" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
  • An AI judge read all 317 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
  • Supports UI / widget rendering.Pass

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 →

Install

How do I install the Jean — Molecular Biology & Genomics MCP server?

Jean — Molecular Biology & Genomics is a hosted endpoint at https://jeanslabs.vercel.app/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.

Common questions

What is the Jean — Molecular Biology & Genomics MCP server?

Jean — Molecular Biology & Genomics is an MCP server listed in the public MCP registry as io.github.genmnz/jean. Validated molecular biology tools: cloning, primers, CRISPR, Sanger, alignment, qPCR, phylogenetics. This page covers its hosted endpoint (https://jeanslabs.vercel.app/mcp).

Is the Jean — Molecular Biology & Genomics MCP server safe to use?

Jean — Molecular Biology & Genomics scores 72 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 Jean — Molecular Biology & Genomics MCP server require authentication?

No. We connected to Jean — Molecular Biology & Genomics without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Jean — Molecular Biology & Genomics MCP server still maintained?

Jean — Molecular Biology & Genomics is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
