MCP tools · 2 exposed · ~191 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
scan_mcp_fleet ~93

Report every MCP server configured on this machine, grouped by the tool it is configured in, with what each one can do and what it costs the context window. Runs locally; no inventory is uploaded. Local servers are not started unless launch_local is set, because starting one runs its code.

NameTypeReqDescription
launch_localboolean–Start local (stdio) servers in order to scan them. This runs their code.

No output schema declared.

No examples provided.

scan_mcp_server ~98

Scan one MCP server and return its full report: cost, which tools can change data or reach the network, and any findings. Give either a remote url or a local launch command. Supplying a command will run it, which starts that server on this machine; a url is connected to and starts nothing.

NameTypeReqDescription
commandstring–Local launch command; running it starts the server.
urlstring–Remote MCP endpoint.

No output schema declared.

No examples provided.

Common questions

What is the mcpgawk MCP server?

mcpgawk is an MCP server listed in the public MCP registry as io.github.gawk-dev/mcpgawk. Measure MCP servers, pin the approved tool surface, refuse calls to tools that changed. Local-first. This page covers its PyPI package (mcpgawk).

Is the mcpgawk MCP server safe to use?

mcpgawk scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. 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 mcpgawk MCP server expose?

mcpgawk exposes 2 tools: scan_mcp_fleet, scan_mcp_server. Their descriptions and schemas cost roughly 191 tokens of context every time the server is loaded.

Is the mcpgawk MCP server still maintained?

mcpgawk is still listed as active in the MCP registry. We last reached this channel on 4 November 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 mcpgawk MCP server under?

mcpgawk 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.
