 The client retries up to 5 times with exponential backoff (1s, 2s, 4s, 8s, 16s, capped at 60s). If the server is fundamentally unreachable, it gives up after 5 attempts. Check the server process and network connectivity.
 
-### feishu-mcp causes EPIPE / "write EPIPE" errors in stdio mode
-
-Many community MCP servers (e.g. `cso1z/Feishu-MCP`) emit console.log/warn output to stdout *before* the JSON-RPC handshake begins. This corrupts the stdio stream, causing `httpx.ReadError` on the Hermes side and EPIPE errors in the Node process.
-
-**Symptoms:**
-- `Error: write EPIPE` in the MCP server process
-- `httpx.ReadError` or `Session termination failed: All connection attempts failed` in Hermes logs
-- Tools register briefly then immediately fail on first use
-
-**Solution — use HTTP transport instead of stdio:**
-
-1. Run feishu-mcp as a persistent HTTP server behind a systemd service:
-
-```bash
-# Install globally
-npm install -g feishu-mcp
-
-# Create systemd user service at ~/.config/systemd/user/feishu-mcp.service
-[Unit]
-Description=Feishu MCP Server
-After=network.target
-
-[Service]
-Type=simple
-Restart=always
-RestartSec=5
-ExecStart=/root/.hermes/node/bin/node /root/.hermes/node/lib/node_modules/feishu-mcp/dist/index.js --log-level=none --feishu-app-id=YOUR_APP_ID --feishu-app-secret=YOUR_APP_SECRET --feishu-auth-type=tenant --enabled-modules=document,task
-StandardOutput=null
-StandardError=journal
-
-[Install]
-WantedBy=default.target
-```
-
-2. Reload and start the service:
-```bash
-systemctl --user daemon-reload
-systemctl --user enable --now feishu-mcp
-```
-
-3. Configure Hermes to connect via HTTP instead of stdio:
-```yaml
-mcp_servers:
-  feishu:
-    url: http://127.0.0.1:3333/mcp
-    timeout: 120
-    connect_timeout: 60
-```
-
-4. Restart Hermes gateway: `hermes gateway restart`
-
-5. Verify: `hermes mcp test feishu` — should show "✓ Connected" with tools listed.
