mcp-server@0.3.19
VERIFIED· not startedPublisher claims: "Model Context Protocol server for live mdedit.ai document collaboration." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Not started: dependency install failed; the server itself was not observed.- Tested
- the dependency install step · every file read, file written and host contacted by what ran
- Not tested
- server startup · the tool list · tool behavior
What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
POSTHOG_PROJECT_TOKENPOSTHOG_PROJECT_TOKEN_COWRITEConfiguration, not credentials: MDEDIT_MCP_INLINE_EDITOR, POSTHOG_HOST- Where it talks to
- mdedit.ai (its own)Also posthog.com, amazonaws.com, youtube-nocookie.com, vimeo.com, cowrite.dev — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- server startup · the tool list · tool behavior
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names posthog.com, amazonaws.com, youtube-nocookie.com, vimeo.com, cowrite.dev as well as its own vendor. The guard injects POSTHOG_PROJECT_TOKEN, POSTHOG_PROJECT_TOKEN_COWRITE only into requests to mdedit.ai (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-14 and scored it 92/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Cost to the agent
Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
