Reads `mcp_servers` from `~/.hermes/config.yaml` +2. For each server, spawns a connection in a dedicated background event loop +3. Initializes the MCP session and calls `list_tools()` to discover available tools +4. Registers each tool in the Hermes tool registry + +### Tool Naming Convention + +MCP tools are registered with the naming pattern: + +``` +mcp_{server_name}_{tool_name} +``` + +Hyphens and dots in names are replaced with underscores for LLM API compatibility. + +Examples: +- Server `filesystem`, tool `read_file` → `mcp_filesystem_read_file` +- Server `github`, tool `list-issues` → `mcp_github_list_issues` +- Server `my-api`, tool `fetch.data` → `mcp_my_api_fetch_data` + +### Auto-Injection + +After discovery, MCP tools are automatically injected into all `hermes-*` platform toolsets (CLI, Discord, Telegram, etc.). This means MCP tools are available in every conversation without any additional configuration. + +### Connection Lifecycle + +- Each server runs as a long-lived asyncio Task in a background daemon thread +- Connections persist for the lifetime of the agent process +- If a connection drops, automatic reconnection with exponential backoff kicks in (up to 5 retries, max 60s backoff) +- On agent shutdown, all connections are gracefully closed + +### Idempotency + +`discover_mcp_tools()` is idempotent -- calling it multiple times only connects to servers that aren't already connected. Failed servers are retried on subsequent calls. + +## Transport Types + +### Stdio Transport + +The most common transport. Hermes launches the MCP server as a subprocess and communicates over stdin/stdout. + +```yaml +mcp_servers: + filesystem: + command: "npx" + args: ["-y", "@modelcontextprotocol/server-filesystem", "/home/user/projects"] +``` + +The subprocess inherits a **filtered** environment (see Security section below) plus any variables you specify in `env`. + +### HTTP / StreamableHTTP Transport + +For remote or shared MCP servers. Requires the `mcp` package to include HTTP client support (`mcp.client.streamable_http`). + +```yaml +mcp_servers: + remote_api: + url: "https://mcp.example.com/mcp" + headers: + Authorization: "Bearer sk-..." +``` + +If HTTP support is not available in your installed `mcp` version, the server will fail with an ImportError and other servers will continue normally. + +## Security + +### Environment Variable Filtering + +For stdio servers, Hermes does NOT pass your full shell environment to MCP subprocesses. Only safe baseline variables are inherited: + +- `PATH`, `HOME`, `USER`, `LANG`, `LC_ALL`, `TERM`, `SHELL`, `TMPDIR` +- Any `XDG_*` variables + +All other environment variables (API keys, tokens, secrets) are excluded unless you explicitly add them via the `env` config key. This prevents accidental credential leakage to untrusted MCP servers. + +```yaml +mcp_servers: + github: + command: "npx" + args: ["-y", "@modelcontextprotocol/server-github"] + env: + # Only this token is passed to the subprocess + GITHUB_PERSONAL_ACCESS_TOKEN: "ghp_..." +``` + +### Credential Stripping in Error Messages + +If an MCP tool call fails, any credential-like patterns in the error message are automatically redacted before being shown to the LLM. This covers: + +- GitHub PATs (`ghp_...`) +- OpenAI-style keys (`sk-...`) +- Bearer tokens +- Generic `token=`, `key=`, `API_KEY=`, `password=`, `secret=` patterns + +## Troubleshooting + +### "MCP SDK not available -- skipping MCP tool discovery" + +The `mcp` Python package is not installed. Install it: + +```bash +pip install mcp +``` + +### "No MCP servers configured" + +No `mcp_servers` key in `~/.hermes/config.yaml`, or it's empty. Add at least one server. + +### "Failed to connect to MCP server 'X'" + +Common causes: +- **Command not found**: The `command` binary isn't on PATH. Ensure `npx`, `uvx`, or the relevant command is installed. +- **Package not found**: For npx servers, the npm package may not exist or may need `-y` in args to auto-install. +- **Timeout**: The server took too long to start. Increase `connect_timeout`. +- **Port conflict**: For HTTP servers, the URL may be unreachable. + +### "MCP server 'X' requires HTTP transport but mcp.client.streamable_http is not available" + +Your `mcp` package version doesn't include HTTP client support. Upgrade: + +```bash +pip install --upgrade mcp +``` + +### Tools not appearing + +- Check that the server is listed under `mcp_servers` (not `mcp` or `servers`) +- Ensure the YAML indentation is correct +- Look at Hermes Agent startup logs for connection messages +- Tool names are prefixed with `mcp_{server}_{tool}` -- look for that pattern + +### Connection keeps dropping + +The client retries up to 5 times with exponential backoff (1s, 2s, 4s, 8s, 16s, capped at 60s).
