Generates Rust documentation and returns structured output with warning count.
AI agents invoke doc to trigger actions in Http. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Generating documentation involves executing a build tool or compiler process (like `cargo doc`), which runs code and external commands. While it is largely read-only in terms of data, it executes processes and writes generated output files, making Execute the most appropriate category.
From the tool's definition 'Generates Rust documentation' implies running a build/doc tool (e.g., `cargo doc`) which executes external processes
Documented attack patterns abuse exactly the kind of access doc gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Http, and nothing reaches the server without passing your rules. This is the rule we recommend for doc:
{
"version": "1",
"default": "deny",
"tools": {
"doc": {
"limits": [
{
"counter": "doc_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}doc stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Generates Rust documentation and returns structured output with warning count. It is categorised as a Execute tool in the Http MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Http MCP server in PolicyLayer and add a rule for doc: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Http. Nothing to install.
doc is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the doc rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for doc. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
doc is provided by the Http MCP server (@paretools/http). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Http, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
