## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- `revoke`

Output parameters:

- `result` (object)

Output parameters:

## Common questions

### 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 71 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 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 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 20 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 Likerts MCP server under?

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.
