How do I install the janusmcp mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `SUPABASE_ACCESS_TOKEN`, `JANUS_CONFIG`, `GOOGLE_OAUTH_CLIENT_ID`, `JANUS_HTTP_HOST`, `REPLACE_ACTIVECAMPAIGN_MCP_URL`, `GOOGLE_OAUTH_CLIENT_SECRET` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Janusmcp MCP Server?

Local multi-account MCP broker — one endpoint, every account. Switch identity without reconnecting.

What it actually does

One-click buttons require the npm package to be published. See RELEASING.md.

Add N accounts once — for the same service and keep them all available
Switch identity without reconnecting — — no re-login, no fiddling with config
Works with any LLM client — — it just speaks standard MCP (stdio + Streamable HTTP)
Works without an MCP session too — — agents can drive it directly from the CLI
Runs locally — — your machine, your keychain, your control
Keeps the context clean — — it exposes only the active account's tools, not N×tools
