Secure an agent system as a permission surface — what authority each tool call runs under, where the confused deputy sits, which controls are enforced outside the model and which are only prompt text, and how far one bad call reaches. Use when granting an agent tools or credentials, wiring in MCP servers or subagents, reviewing an agent that acted beyond what the requester could have done, or before letting an agent touch a shared or production system. Not for wording the ingestion trust…
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
# Agent security An agent's security properties come from the tools and credentials it holds, not from how carefully its prompt is written. The design question is never "would the model refuse?" — it is "what happens when it does not?" ## When this fires An agent or subagent is being given tools, credentials or an MCP server; an agent is about to reach a shared, production or third-party system; an agent did something the person asking could not have done themselves; an agent system is being reviewed. It does not fire for a model with no tools and no outward surface. ## Procedure 1. **Write down the authority.** Every tool, every credential, every system reachable, and whose identity each call actually runs as. Most agent systems have never had this written down, and the exercise alone usually finds the problem. 2. **Find the confused deputy.** Wherever a call runs under a service account rather than the requester, the agent can be asked to do what the requester may not. Either pass the requester's own scoped identity through to the system being called, or restrict the service account to the …

How to install
mdr add nahid-sparktales/agent-dispatcher/agent-security@sha256:0cc6ee01b07f8452The line at the top of this page pins the label git:20260919.a0d4f55, 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.
