## MCP tools (4)

### `lookup_server` (~149 tokens)

Look up an MCP server's evidence

Look up one MCP server, or one package, in the local agentgate evidence index. Use this when you know what you are asking about and want its record: the verdict, the coverage block (which scanners ran, which did not, and why), and the findings. Do not use it to check a list of tools you use; inventory_tools answers that question and returns one line per tool instead. A record that is incomplete is reported as incomplete, never as clean.

Input parameters:

- `package` (string): Package name, for example @scope/pkg
- `server` (string): Registry server name, for example org.example/tools
- `version` (string): Exact version, to narrow a package match

Output parameters:

- `found` (boolean): false means this index has no such record; it is not a statement that the tool is safe or that it does not exist
- `indexGeneratedAt` (string|null)
- `indexWarning` (string): Present only when the server was started with a note about the index it loaded.
- `multiple` (boolean): present when found is true
- `query` (object): present when found is false, echoing what was asked
- `record` (object): One index record, reduced to what a reader can act on.
- `records` (array): present instead of record when several matched; at most ten are listed

### `inventory_tools` (~105 tokens)

Match a list of tools against the index

Given the MCP servers and agent tools you actually use, report which ones the index has evidence for, which need your exact version, and which it has never measured. Use this to audit a list of what you run; for a single server or package, lookup_server returns the whole record rather than a one-line state. Nothing is uploaded and nothing is executed.

Input parameters:

- `tools` (array, required): One entry per tool: a name, or an object with name/server/package/registry/version.

Output parameters:

- `indexWarning` (string): Present only when the server was started with a note about the index it loaded.
- `items` (array)
- `summary` (object)

### `coverage_report` (~89 tokens)

How much of the index was actually measured

Report the coverage distribution of the whole index: how many records are fully measured, what stopped the rest, and how many findings came out of the work that ran. Use this before quoting any percentage from this server, because it is the denominator; it is the same number the project quotes in public. It answers a question about the index, not about one tool: for one tool, use lookup_server.

Output parameters:

- `completedRuns` (integer)
- `cross` (object)
- `findings` (object)
- `findingsTotal` (integer)
- `generatedAt` (string|null)
- `indexWarning` (string): Present only when the server was started with a note about the index it loaded.
- `perScanner` (object)
- `problems` (array)
- `reasons` (object)
- `requiredRuns` (integer)
- `scanner` (string|null)
- `states` (object)
- `total` (integer)
- `verdictIncompleteButComplete` (integer)
- `verdicts` (object)

### `check_project` (~155 tokens)

Scan a local project for refused configuration

Run agentgate's own checks over a local directory: MCP client configuration, hooks, manifests and source patterns a policy would refuse. Use it on a project you can read; it is not a record lookup, so for one server's record use lookup_server and for a list of tools use inventory_tools. It only reads files; it does not install, execute or upload anything, and it does not scan the network.

Input parameters:

- `exclude` (string): Comma-separated directories to skip. Defaults to node_modules,.git
- `policy` (string): Path to an agentgate.policy.json. Defaults to the one in root, or the built-in default.
- `root` (string): Directory to check. Defaults to the working directory.

Output parameters:

- `coverage` (object): what the policy could not measure: a check that failed, and evidence the index did not have
- `findings` (array)
- `indexWarning` (string): Present only when the server was started with a note about the index it loaded.
- `policyVersion` (string)
- `relatedRecords` (integer)
- `root` (string)
- `verdict` (string): clean, findings or incomplete; incomplete is not a pass

## Common questions

### What is the agentgate MCP server?

agentgate is an MCP server listed in the public MCP registry as io.github.ciceroyang/agentgate. Read-only evidence for the tools agents run: MCP server records, coverage and policy. This page covers its npm package (@zhiliangtech/agentgate).

### Is the agentgate MCP server safe to use?

agentgate scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 22 September 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.

### What tools does the agentgate MCP server expose?

agentgate exposes 4 tools: lookup_server, inventory_tools, coverage_report, check_project. Their descriptions and schemas cost roughly 498 tokens of context every time the server is loaded.

### Is the agentgate MCP server still maintained?

agentgate is still listed as active in the MCP registry. We last reached this channel on 22 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 agentgate MCP server under?

agentgate declares the AGPL-3.0-only licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
