# mcpx
`mcpx` turns registered MCP servers into an agent-friendly command surface.
Use it when a task needs MCP-backed services such as PostHog, Sentry, Cloudflare,
or another server registered in the user's global mcpx registry.
## Execution Rules
- Run `mcpx` directly.
- Start with the server inventory instead of dumping every registered schema.
- Call MCP tools as `mcpx <server> <tool> --input <json>`.
- Pass all tool arguments through `--input`; do not invent flags for MCP tool fields.
- Use focused schema selectors before calling tools on large MCP surfaces.
- Do not hand-edit `~/.agents/mcpx/servers.json` or token cache files unless the user explicitly asks for registry surgery.
- Treat MCP server registration and OAuth setup as human-owned configuration. If a required server is missing or unauthenticated, stop and ask the user to configure it.
## First Move: Discover The Surface
At the start of an MCP task, run bare `mcpx` to list configured servers:
```bash
mcpx
```
Choose the likely server from the user's request, then inspect only that server's
schema:
```bash
mcpx --schema=.sentry
mcpx --schema=.posthog
```
After that, narrow to the specific tool or a short candidate list:
```bash
mcpx --schema=.posthog.projects-get
mcpx --schema='.posthog.{projects-get,alerts-list,alert-create}'
```
Avoid `mcpx --schema` unless the user explicitly asks for the complete command
surface. On a real registry it may expand every server schema and waste the
agent context.
