Issues

These describe what this server's manifest declares. A product can provide controls that MCP has no way to express — token revocation, an admin console, audit logs — and this page cannot see them. The absence of a declaration is not evidence that a control is absent.

critical · no-revocation · All 6 tools

6 of 6 tools declare no way for the customer to switch them off once granted. This applies to every tool because MCP has no field in which to declare a revocation mechanism; the product may provide one outside MCP that a manifest cannot show.

high · no-expiry · All 6 tools

6 of 6 tools declare no expiry. This applies to every tool because MCP has no field in which to declare an expiry; the product may provide one outside MCP that a manifest cannot show.

high · no-audit-trail · All 6 tools

6 of 6 tools declare no record of their actions that the customer can read. This applies to every tool because MCP has no field in which to declare an audit requirement; the product may provide one outside MCP that a manifest cannot show.

low · uncapped-read · All 6 tools

6 tools can read data and declare no limit.

Declared capabilities

How each tool was read. declared means the server's own annotation said so — self-reported and unverified. inferred is from the tool's name. assumed means nothing indicated either way.

Answering this question about your own agent? Media Yard LLC runs a fixed-scope Agent Permission Audit: the same reading applied to your agent surface, delivered as a dated artifact you can hand to a customer's security review. See what it includes and costs, or write to support@leashkit.com. Buying one does not change this page, its score or its place in the index — see Independence.

Maintain this server? If this page misreads your manifest, or your server has changed, submit its current tools/list response and it will be re-scored and dated. Corrections are published alongside the original, not in place of it.

Scores describe capability as declared in each server's own tools/list response, on the date shown. MCP tool annotations are written by the server being described and are not verified. A score is not a certification, not a penetration test, and not a statement that software is safe or unsafe. Methodology. Generated 2026-09-14.

The Leash Index is not affiliated with, sponsored by or endorsed by the owners of the servers it lists; product names are used only to identify them. A maintainer verified listing means its maintainer submitted the manifest, not that they endorse this index. No one can pay for a score, a ranking, a listing or a removal.
