nextcloud-organizer-mcp@0.2.2
VERIFIED· not startedPublisher claims: "MCP server for managing Nextcloud tasks, calendars and notes via natural language" 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

- no vendor host named in the codeAlso owncloud.org, nextcloud.com, apple.com, your-domain.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 owncloud.org, nextcloud.com, apple.com, your-domain.com as well as its own vendor. The guard injects MCP_OAUTH_ACCESS_TOKEN_EXPIRY_SECONDS, MCP_OAUTH_ALLOWED_REDIRECT_DOMAINS, MCP_OAUTH_PASSWORD, MCP_OAUTH_REFRESH_TOKEN_EXPIRY_SECONDS, MCP_OAUTH_STATE_DIR only into requests to the host you bind (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 2026-11-13 and scored it 84/100 (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.

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.
