Yaw MCP - MCP orchestrator CLI. Runs every MCP server locally from a JSON file you control. Token-budget aware: dispatch ranks servers against the current task and loads only what's needed instead of every tool description. Free for personal use. See yaw.sh/mcp for the recommended npm install -g path.
npx -y @yawlabs/mcp
Lint your AI agent context files, MCP server configs, and session data against your actual codebase. Catches broken paths, wrong commands, stale context, and token waste. Includes built-in MCP server.
npx -y @yawlabs/ctxlint
MCP spec compliance test suite. Tests any MCP server against the 2025-11-25 specification. CLI tool and MCP server for automated validation of tool schemas, error handling, and protocol behavior.
npx -y @yawlabs/mcp-compliance
Manage your Tailscale tailnet from AI assistants. 89 admin-API tools (plus 4 opt-in local-CLI diagnostics) covering devices, ACLs, DNS, auth keys, users, webhooks, posture management, and Tailscale Services. HuJSON formatting preservation and ETag-safe ACL updates.
npx -y @yawlabs/tailscale-mcp
npm registry intelligence for AI assistants. Package search, security audits, dependency analysis, download stats, version comparison, and org management.
npx -y @yawlabs/npmjs-mcp
MCP server for SSH operations with built-in diagnostics. Execute commands on remote hosts, transfer files, manage tunnels, and troubleshoot connectivity issues from any MCP client.
npx -y @yawlabs/ssh-mcp
Query PostgreSQL from AI assistants. Read-only by default (writes opt in via ALLOW_WRITES=1); extended-query protocol closes the stacked-query SQL injection class. 21 tools: schema introspection, EXPLAIN with optional HypoPG hypothetical indexes, pg_stat_statements diagnostics, lock inspection, role/privilege awareness. Drop-in replacement for the deprecated @modelcontextprotocol/server-postgres.
npx -y @yawlabs/postgres-mcp
Electron.js MCP server. IPC scaffolding, security auditing, build tooling, and development intelligence for AI assistants working on Electron apps. Pairs with electron-optimize, our drop-in utilities library for temp file cleanup, window bounds validation, startup timing, and cache management.
npx -y @yawlabs/electron-mcp
Manage Caddy web servers via the admin API. Configure reverse proxies, manage TLS certificates, update routes, and control Caddy instances from AI assistants.
npx -y @yawlabs/caddy-mcp
HTTP fetch with guardrails. SSRF protection (blocks private IPs, RFC 1918, cloud metadata endpoints), HTML-to-markdown, reader-mode extraction, metadata / link / sitemap / RSS-Atom parsing, and robots.txt verdicts. Designed for AI assistants that need to read the web without becoming a vector for blind-SSRF attacks against your internal network.
npx -y @yawlabs/fetch-mcp
Call any AWS API from AI assistants. One generic aws_call tool covers the full CLI surface, seven aws_resource_* tools wrap Cloud Control API for generic CRUD across hundreds of resource types (including a diff that simulates JSON-Patch updates locally before they hit AWS), and a device-code SSO flow handles mid-session token expiry without dropping you to a terminal.
npx -y @yawlabs/aws-mcp
Twelve MCP servers means twelve install commands, twelve configs to keep in sync, and twelve things that can break - and that is on one client. Multiply by every MCP client you use and the JSON pile grows fast. Yaw MCP - pre-installed in Yaw Terminal, or npm install -g @yawlabs/mcp standalone - is one CLI that runs every MCP server locally from a JSON file you control, no account required for personal use. yaw mcp install <client> wires up whichever client you use, then keeps every server in one place.
All 12 servers are published on npm and maintained by Yaw Labs. Eleven are MIT-licensed open source; the twelfth is the Yaw MCP orchestrator (freemium, source on GitHub).
