permisapi-mcp@0.6.1

VERIFIED· not started

Publisher claims: "Serveur MCP pour PermisAPI : 18 outils en lecture seule pour interroger plus de 3 millions de permis de construire en France (autorisés depuis 2013) depuis Claude, ChatGPT, Claude Desktop, Cursor, Windsurf et tout client MCP. Argument facultatif type (PC, DP, PA ou PD) sur les outils qui prennent un numéro, champs type_autorisation et identifiant, connexion OAuth au serveur hébergé, année de dépôt filtrable dès 2000." 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
DATABASE_URLMCP_SECRET_RELAISPERMISAPI_KEYPOSTHOG_API_KEYSECRET_KEYConfiguration, not credentials: MCP_BASE_URL, MCP_CLE_JETONS, MCP_DUREE_JETON_ACCES, MCP_REPONDRE_DISCOVER, PERMISAPI_BASE_URL, POSTHOG_HOST
Where it talks to
permisapi.fr (its own)Also posthog.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 posthog.com as well as its own vendor. The guard injects DATABASE_URL, MCP_SECRET_RELAIS, PERMISAPI_KEY, POSTHOG_API_KEY, SECRET_KEY only into requests to permisapi.fr (and its subdomains) and refuses the rest.

$vet-skills run --secrets DATABASE_URL=permisapi.fr,MCP_SECRET_RELAIS=permisapi.fr,PERMISAPI_KEY=permisapi.fr,POSTHOG_API_KEY=permisapi.fr,SECRET_KEY=permisapi.fr -- uvx permisapi-mcp

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 80/100 (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.
