Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency100
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to geml-spec/geml). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 2 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability0

  • Stability not yet verified: this package installed, but its server did not start, so we have no schema to compare.Unverified
Tool Coverage0
  • Tool coverage not yet verified: this package installed, but its server did not start, so we have no tool definitions to assess.Unverified
Tool Safety0
  • Tool safety not yet verified: this package installed, but its server did not start, so we have no tool text to scan.Unverified
Capabilities0
  • Protocol version not yet verified: this package installed, but its server did not start, so we never saw its MCP handshake.Unverified

Unverified: 5 categories

Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you. How we score packages →

Install

How do I install the GEML — a plain-text document format built to be edited in… MCP server?

GEML — a plain-text document format built to be edited in… runs locally as an npm package, launched with npx -y @geml/geml. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools

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 →

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.

Common questions

What is the GEML — a plain-text document format built to be edited in… MCP server?

GEML — a plain-text document format built to be edited in… is an MCP server listed in the public MCP registry as io.github.geml-spec/geml. One section in, one section out, on Markdown/GEML files, bad writes refused. This page covers its npm package (@geml/geml).

Is the GEML — a plain-text document format built to be edited in… MCP server safe to use?

GEML — a plain-text document format built to be edited in… scores 50 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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.

Is the GEML — a plain-text document format built to be edited in… MCP server still maintained?

GEML — a plain-text document format built to be edited in… is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the GEML — a plain-text document format built to be edited in… MCP server under?

GEML — a plain-text document format built to be edited in… declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
