Find the consent gap in an agent skill or MCP server: the distance between the permissions and capabilities it declares and what its bundled code and instructions actually exercise. Covers over-broad grants a skill requests but never uses, capabilities it exercises without declaring, and grants that are used but still wider than the task needs. Read the declared surface in frontmatter or manifest, inventory the real behavior, and diff the two in both directions. Use when reviewing a skill or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auditing declared versus used permissions: the consent gap is the bug A user grants a skill the permissions it asks for. The question no one checks is whether it needs them. A skill that requests shell access and never shells out, or network access and never makes a call, has widened the user's blast radius for nothing, and a compromise or a later update inherits that headroom. Worse is the other direction: a skill that acts beyond what it declared. This skill measures the gap between the grant and the use, in both directions. ## When to use - You are reviewing a skill, an MCP server, or a marketplace entry before install. - You are auditing least privilege across an agent's installed skills and tools. - You want to right-size a grant, not just confirm the artifact runs. ## Scope check Audit skills and servers you own or are authorized to review. Inspect the bundled code statically; run it only in a contained environment. If you can't name the authorization, stop. ## The loop 1. **Read the declared permission surface.** Collect exactly what the artifact asks for: the allowed-tools or capability list in frontmatter or manifest, the …

How to install
mdr add unboundcompute/security-agent-skills/auditing-declared-vs-used-permissions@sha256:e22e35b71edd0fc5The line at the top of this page pins the label git:20260818.ed96156, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
