Configuration Schema by Client ### Standard JSON Schema (Claude Desktop, Cursor, Antigravity, Windsurf, Cline) ```json { "mcpServers": { "": { "command": "", "args": ["", ""], "env": { "": "" } } } } ``` ### OpenAI Codex CLI Schema (`~/.codex/config.toml`) ```toml [mcp_servers.] command = "" args = ["", ""] [mcp_servers..env] = "" ``` ### Zed Editor Schema (`settings.json`) ```json { "context_servers": { "": { "command": { "path": "", "args": ["", ""], "env": { "": "" } } } } } ``` --- ## 3. Top 12 Verified Server Snippets ### 1.

Puppeteer Browser Automation (`@modelcontextprotocol/server-puppeteer`) - **Transport**: STDIO ```json { "mcpServers": { "puppeteer": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-puppeteer"] } } } ``` ### 6. Local Filesystem (`@modelcontextprotocol/server-filesystem`) - **Transport**: STDIO - **Argument**: Absolute or relative directory boundaries ```json { "mcpServers": { "filesystem": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "./"] } } } ``` ### 7. Persistent Memory Graph (`@modelcontextprotocol/server-memory`) - **Transport**: STDIO ```json { "mcpServers": { "memory": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"] } } } ``` ### 8. Docker Daemon (`mcp-server-docker`) - **Transport**: STDIO ```json { "mcpServers": { "docker": { "command": "npx", "args": ["-y", "mcp-server-docker"] } } } ``` ### 9. Slack API (`@modelcontextprotocol/server-slack`) - **Transport**: STDIO - **Required Env**: `SLACK_BOT_TOKEN`, `SLACK_TEAM_ID` ```json { "mcpServers": { "slack": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-slack"], "env": { "SLACK_BOT_TOKEN": "xoxb-xxxxxxxxxxxx", "SLACK_TEAM_ID": "Txxxxxxxx" } } } } ``` ### 10. Sentry Error Tracking (`mcp-server-sentry`) - **Transport**: STDIO - **Required Env**: `SENTRY_AUTH_TOKEN` ```json { "mcpServers": { "sentry": { "command": "uvx", "args": ["mcp-server-sentry", "--auth-token", "sntrys_xxxxxxxxxxxx"] } } } ``` ### 11. Upstash Context7 Docs (`@upstash/context7-mcp`) - **Transport**: STDIO ```json { "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp"] } } } ``` ### 12. Sequential Thinking (`@modelcontextprotocol/server-sequential-thinking`) - **Transport**: STDIO ```json { "mcpServers": { "sequential-thinking": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"] } } } ``` --- ## 4. Common Execution Pitfalls & Troubleshooting 1. **Windows Path Escaping**: When writing file paths in JSON on Windows, always use forward slashes (`"C:/Projects/sandbox"`) or double-escaped backslashes (`"C:\\\\Projects\\\\sandbox"`). Unescaped single backslashes will fail JSON parsing. 2. **Missing Terminal `$PATH` (ENOENT error)**: GUI applications (Claude Desktop, Cursor) do not inherit environment variables from your interactive `.zshrc` or `.bashrc`. If an executable fails with `spawn ENOENT`, specify the full binary path (e.g. `C:/Program Files/nodejs/npx.cmd` or `/usr/local/bin/npx`). 3. **STDOUT Contamination (JSON-RPC code -32603)**: STDIO transports require newline-delimited JSON-RPC messages on STDOUT. Any `console.log()` or print statement emitted by the server corrupts the framing and disconnects the client. Redirect all logs to STDERR. --- ## 5.
