Capabilities FAQs

Question 1

What is Capabilities and its primary function?

Accepted Answer

Capabilities is a developer tool designed to verify and report the supported Model Context Protocol (MCP) capabilities, specifically focusing on protocol versions, of connected hosts or clients. It ensures compatibility within your MCP ecosystem.

Question 2

How does Capabilities check MCP protocol versions?

Accepted Answer

Operating as an MCP server, Capabilities communicates over standard I/O (stdio). It uses the built-in `get_protocol_version` tool to report the protocol version supported by the server and the version sent by the client during initialization.

Question 3

How do I integrate Capabilities into my MCP configuration?

Accepted Answer

Integration is seamless. You simply add Capabilities to your MCP configuration's `mcpServers` section, specifying the command to execute its main script. This allows your MCP client to discover and utilize its features.

Question 4

What specific information does Capabilities provide about protocol versions?

Accepted Answer

When queried, Capabilities returns the `serverProtocolVersion` (the version it supports), the `clientProtocolVersion` (the version reported by the connected client), and a clear, human-readable `message` summarizing the version status and compatibility.

Question 5

Is Capabilities easy to install and use?

Accepted Answer

Yes, Capabilities uses standard Node.js package management for installation (`npm install`) and a simple build command (`npm run build`). Once built, it's easily configured within any existing MCP setup.
