Connect Hermes Agent

Nous Research's open-source agent, a desktop app and CLI that also runs in Telegram, Discord, Slack, WhatsApp, Signal and email.

Before you start

Create an API key on the Agent page in planpo.st and grant only the permissions this agent needs. The key is shown once; replace pk_live_xxx in the snippets below with it. Its posts go out at the time the agent sets; to check each one first, turn on “Require approval before publishing” when you create the key, or later in the key's row on the Agent page.

Local install

Runs the MCP server on your own machine through npx, so your key never leaves it. Needs Node 18 or newer.

Local, via the MCP settings
Add an MCP server by local command:

Command:  npx
Args:     -y planpost-mcp
Env:      PLANPOST_API_KEY=pk_live_xxx

Things that catch people out

  • Hermes manages MCP servers from its settings and a CLI, and servers can be added by URL or by local command. The local command above is the tested path.
  • Hermes documents SSE for remote servers. Our hosted endpoint speaks streamable HTTP, which is the newer transport, so verify a URL connection against your Hermes version before relying on it and use the local command if it does not connect.
  • MCP servers you add are disabled by default in Hermes until you enable them, which is deliberate on their side.

Check it works

Ask the agent to list your connected accounts. If it comes back with them, the tools are available.
