## MCP tools (3)

### `mcp_discover` (~95 tokens)

Search configured servers, cached child tool schemas, and declarative Methods without starting every child. Set refresh=true with a specific server to refresh only that server.

Input parameters:

- `kind` (string): Result kind (default: all)
- `query` (string): Capability search query
- `refresh` (boolean): Connect to the named server and refresh its live schemas
- `server` (string): Filter child tools to one configured server

### `mcp_call` (~82 tokens)

Call one explicitly named child tool. The target starts lazily. Calls are never replayed implicitly after a timeout or transport failure.

Input parameters:

- `args` (object): Arguments passed to the child tool
- `server` (string, required): Configured child server name
- `timeoutMs` (integer): Optional per-call deadline
- `tool` (string, required): Child tool name

### `mcp_run` (~58 tokens)

Run a reviewed declarative Method: a bounded, schema-validated sequence of lazy child calls with typed gaps and trace evidence.

Input parameters:

- `input` (object, required): Method input validated against its JSON Schema
- `method` (string, required): Registered Method name

## Common questions

### What is the MetaMCP MCP server?

MetaMCP is an MCP server listed in the public MCP registry as io.github.mentu-ai/metamcp. Route long-tail MCP servers through three lazy tools and reviewed declarative Methods. This page covers its npm package (@mentu/metamcp).

### Is the MetaMCP MCP server safe to use?

MetaMCP scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 22 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MetaMCP MCP server expose?

MetaMCP exposes 3 tools: mcp_discover, mcp_call, mcp_run. Their descriptions and schemas cost roughly 235 tokens of context every time the server is loaded.

### Is the MetaMCP MCP server still maintained?

MetaMCP is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the MetaMCP MCP server under?

MetaMCP declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
