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 →

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 15 exposed · ~1,379 tokens

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 →

Install

How do I install the io.github.dcadolph/vamoose MCP server?

io.github.dcadolph/vamoose runs locally as a container image, launched with docker run --rm -i -e VAMOOSE_PROVIDER -e VAMOOSE_TIMEZONE ghcr.io/dcadolph/vamoose:v0.35.0 mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

oci · ghcr.io/dcadolph/vamoose:v0.35.0

# add to Claude Code
claude mcp add dcadolph-vamoose -- docker run --rm -i -e VAMOOSE_PROVIDER -e VAMOOSE_TIMEZONE ghcr.io/dcadolph/vamoose:v0.35.0 mcp

This image reads VAMOOSE_PROVIDER and VAMOOSE_TIMEZONE. Set them in your client's env block for this server; docker run -e passes each one through to the container.

Common questions

What is the io.github.dcadolph/vamoose MCP server?

io.github.dcadolph/vamoose is an MCP server listed in the public MCP registry as io.github.dcadolph/vamoose. Calendar workflow engine for time off, approvals, and quick actions on any calendar backend. This page covers its container image (ghcr.io/dcadolph/vamoose:v0.35.0).

Is the io.github.dcadolph/vamoose MCP server safe to use?

io.github.dcadolph/vamoose scores 48 out of 100 on VerifyMCP. 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.

What tools does the io.github.dcadolph/vamoose MCP server expose?

io.github.dcadolph/vamoose exposes 15 tools: whoami, request_time_off, time_off_status, promote_to_team, cancel_hold, and 10 more. Their descriptions and schemas cost roughly 1,379 tokens of context every time the server is loaded.

Is the io.github.dcadolph/vamoose MCP server still maintained?

io.github.dcadolph/vamoose is still listed as active in the MCP registry. We last reached this channel on 5 November 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 io.github.dcadolph/vamoose MCP server under?

io.github.dcadolph/vamoose declares the BUSL-1.1 licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.

What did VerifyMCP test on the io.github.dcadolph/vamoose MCP server?

VerifyMCP ran 11 checks on io.github.dcadolph/vamoose, covering Source repository, Provenance, License, Maintenance and 7 more. 5 items could not be completed, a gap on our side rather than a finding about io.github.dcadolph/vamoose: Malware scan, Known CVEs, Install scripts, Dependency health and 1 more. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a container image, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
