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 →

What is the Likerts MCP server?
Likerts is an MCP server listed in the public MCP registry as io.github.crosstabs/likerts. Manage open-source in-product surveys, collections, responses and exports with scoped access. This page covers its npm package (@likerts/mcp).
Is the Likerts MCP server safe to use?
Likerts scores 76 out of 100 on VerifyMCP. We recorded 7 known advisories against it as of 5 November 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 Likerts MCP server expose?
Likerts exposes 33 tools: surveys_create, surveys_list, surveys_update, surveys_publish, collections_create, and 28 more. Their descriptions and schemas cost roughly 1,572 tokens of context every time the server is loaded.
Is the Likerts MCP server still maintained?
Likerts is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

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