Makes an HTTP POST request via curl and returns structured response data. Convenience wrapper for the request tool with required body.
AI agents invoke post to trigger actions in Lint. 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.
This tool executes arbitrary HTTP POST requests via curl to any URL with any body content. It triggers external operations whose effects depend entirely on the arguments provided — it could submit forms, call APIs, trigger webhooks, or perform any number of side effects on external systems.

Documented attack patterns abuse exactly the kind of access post gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Lint, and nothing reaches the server without passing your rules. This is the rule we recommend for post:
{
"version": "1",
"default": "deny",
"tools": {
"post": {
"limits": [
{
"counter": "post_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}post 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.

Makes an HTTP POST request via curl and returns structured response data. Convenience wrapper for the request tool with required body. It is categorised as a Execute tool in the Lint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Lint MCP server in PolicyLayer and add a rule for post: 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 Lint. Nothing to install.
post 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 post 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 post. 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.
post is provided by the Lint MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Lint, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
