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)

**Unverified: 5 categories.** Categories scored 0 because our sandbox could not run this package, so we have no schema for these checks to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until we can run it.

## Install

### How do I install the agent-custody MCP server?

agent-custody runs locally as an npm package, launched with npx -y @agent-custody/receipts gateway, plus the required --config, which you supply. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## Common questions

### What is the agent-custody MCP server?

agent-custody is an MCP server listed in the public MCP registry as io.github.svayatta/agent-custody. MCP gateway that checks each agent tool call against a signed grant and policy, and signs a receipt. This page covers its npm package (@agent-custody/receipts).

### Is the agent-custody MCP server safe to use?

agent-custody scores 49 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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.

### Is the agent-custody MCP server still maintained?

agent-custody 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.

### What licence is the agent-custody MCP server under?

agent-custody declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the agent-custody MCP server?

VerifyMCP ran 9 checks on agent-custody, covering Malware scan, Known CVEs, Install scripts, Dependency health and 5 more. 5 items could not be completed, a gap on our side rather than a finding about agent-custody: Schema quality, Stability, Tool coverage, Tool safety and 1 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
