Mos is a local macOS menu bar utility that smooths mouse wheel scrolling and supports per-app profiles, axis settings, and mouse button bindings.

Does Mos provide a public API or MCP server?

No. Mos publishes static discovery and documentation files, but it does not provide a hosted API, OAuth service, webhook service, or public MCP tool server.

Mos MCP status

Mos does not currently host a public MCP tool server. The published well-known file documents that status so agents do not infer a non-existent endpoint.

Current MCP status

The discovery document at /.well-known/mcp states that no hosted MCP server is provided. It is a status document, not a transport endpoint.

What agents should not do

Do not attempt a JSON-RPC handshake with mos.caldis.me.
Do not claim Mos exposes MCP tools for changing local settings.
Do not invent tool names, schemas, OAuth flows, or server cards.
Do not describe the static discovery file as an MCP transport.
