EchoRelay is a multi-tenant HTTP relay: callers hit your versioned API lines, EchoRelay authenticates, rate-limits, and bills the request, then fans it out to your target URLs with retries and a dead-letter queue. The MCP server is the management plane — your agent can set up and operate a project end to end: create lines and endpoints, dry-run endpoint configs, manage API keys and key policies, invite team members, check billing and credits, read request logs and metrics, and retry or discard DLQ entries. Every tool carries read-only/destructive annotations, so MCP hosts can auto-approve reads and confirm destructive actions. Authentication is a Bearer token created in the EchoRelay panel.

One persistent tmux-backed terminal for AI agents. ssh, docker exec, and REPLs nest inside a single authenticated session (no re-auth per command). Token-reduced reads, 4-layer completion detection, and a human can co-drive via the shared tmux socket. Install: npx -y aiterm-mcp

A small MCP server for coding agents. Catches dead model IDs, dependencies with open CVEs, and end-of-life runtimes — the things training data is months stale on — before the agent ships broken code. Free, no auth, stateless. Three tools, three output modes, auditable {as_of, sources[]} on every response.

AppContext is a personal MCP hub for macOS that aggregates all your MCP servers behind one endpoint, plus gives AI coding agents live visual context from your iOS simulator and Chrome browser.
