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 151864 tokens (~477/item across 318 items; 317 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 (98% 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 319 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

Checks we ran (13)

  • TLS certificate
  • HTTPS
  • HSTS header

Checks we could not complete (1)

These are gaps on our side, not findings about this hosted endpoint. We only credit what we can confirm, so a category made up entirely of them scores 0.

  • Authorization in Endpoint SecurityAuthorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.

Does not apply to this hosted endpoint (2)

  • Supply Chain SecurityScored on package channels only. This is a hosted endpoint, so there is nothing to install or inspect.
  • Provenance & TransparencyScored on package channels only. This is a hosted endpoint, so there is nothing to install or inspect.

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.

What did VerifyMCP test on the Jean — Molecular Biology & Genomics MCP server?

VerifyMCP ran 13 checks on Jean — Molecular Biology & Genomics, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 9 more. One item could not be completed, a gap on our side rather than a finding about Jean — Molecular Biology & Genomics: Authorization. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
