overleaf-mcp-plus@0.3.1

VERIFIED· not started

Publisher claims: "The most comprehensive MCP server for Overleaf — full CRUD, compile, PDF download, git history, diff, and more. (The `overleaf-mcp` name on PyPI is taken by a smaller read-only project, hence the `-plus` suffix; the CLI command is still `overleaf-mcp`.)" 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
OVERLEAF_GIT_AUTHOR_EMAILOVERLEAF_GIT_AUTHOR_NAMEOVERLEAF_GIT_TOKENConfiguration, not credentials: DIFF_CONTEXT_LINES, DIFF_MAX_OUTPUT_CHARS, HISTORY_LIMIT_DEFAULT, HISTORY_LIMIT_MAX, OVERLEAF_BASE_URL, OVERLEAF_GIT_HOST, OVERLEAF_PULL_TTL, OVERLEAF_PUSH_BACKOFF, OVERLEAF_PUSH_RETRIES, OVERLEAF_SESSION, OVERLEAF_TEMP_DIR
Where it talks to
no vendor host named in the codeAlso overleaf.com — 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 overleaf.com as well as its own vendor. The guard injects OVERLEAF_GIT_AUTHOR_EMAIL, OVERLEAF_GIT_AUTHOR_NAME, OVERLEAF_GIT_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx overleaf-mcp-plus

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 81/100 (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.
