Add, authenticate, list, and remove MCP (Model Context Protocol) servers — connect any external tool or service that publishes an MCP endpoint to the assistant.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Configure MCP servers to give the assistant access to any external tool or service that publishes an MCP endpoint. **DO NOT** run exploratory commands. Do not check available CLI commands, search for bun/npx/node, or investigate transport types. Follow the steps below exactly and stop when done. (Looking up a service's MCP endpoint URL in its own documentation is allowed when the service is not in the recipe table, per Step 3.) ## When to Use USE THIS SKILL WHEN: - User asks to connect any external tool or service via MCP - User asks "what MCP servers / integrations do I have?" - An MCP tool returns an auth error → run `assistant mcp auth <name>` - User wants to disconnect an integration ## Prefer Native OAuth Integration (check this first) Many services have built-in OAuth integrations that are simpler and more reliable than MCP. Before setting up MCP, check whether the service already has a native OAuth provider: ``` assistant oauth providers list ``` If the service appears in that list, connect it natively instead of using MCP: ``` assistant oauth connect <provider> ``` **Only use MCP when:** - The service is not in `assistant oauth providers list` …

How to install
mdr add vellum-ai/vellum-assistant/mcp-setup@sha256:490ee1ed55ff69a5The line at the top of this page pins the label git:20260914.25fbd03, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
