Connect to external APIs, webhooks and internet services through standard HTTP requests. Build integrations with virtually any platform that exposes a web-based interface.
Hermes is Nous Research's command-line agent. MCP servers are declared in its YAML config and reloaded without a restart.
This guide connects HTTP to Hermes through MewCP, so Hermes can use HTTP's 1 tool, like http_request.
HTTP needs no credentials, but every call still runs through MewCP: scoped, checked and logged like any other.
Scope access to the exact HTTP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.

Other clients
HTTP works the same way in every client below. Pick yours for its own guide.
Free to start.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
Edit config.yaml in your Hermes config directory (~/.hermes).
Put this under the top-level "mcp_servers:" key.
Run /reload-mcp in Hermes, or start a fresh session. Sign in when the browser window opens.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Perform a generic HTTP/HTTPS request and return status, headers, and body.
