send-post-request · Api Testing MCP: Risk & Policy

WHAT IT DOES

What send-post-request does on Api Testing

AI agents use send-post-request to create or update resources in Api Testing — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Api Testing environment.

WHY IT NEEDS A POLICY

Why send-post-request needs a policy

HTTP POST requests create or modify data, classifying this as Write. Severity is high because a POST request sent to an arbitrary API endpoint could create unintended records, modify state, or trigger side effects depending on the target API. However, it falls short of critical since POST is generally reversible (created data can be deleted) and financial harm is not intrinsic to the method itself.

From the tool's definition Tool name 'send-post-request' and description 'send the post request' indicates HTTP POST method capability. POST is used to create or modify data on a server. The server description confirms 'Enables HTTP API testing (GET, POST, PUT, DELETE)'.

Verdict

send-post-request Rate-limited

send-post-request stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about send-post-request

What does the send-post-request tool do? +

send the post request. It is categorised as a Write tool in the Api Testing MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on send-post-request? +

Register the Api Testing MCP server in PolicyLayer and add a rule for send-post-request: 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 Api Testing. Nothing to install.

What risk level is send-post-request? +

send-post-request is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit send-post-request? +

Yes. Add a rate_limit block to the send-post-request 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.

How do I block send-post-request completely? +

Set action: deny in the PolicyLayer policy for send-post-request. 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.

What MCP server provides send-post-request? +

send-post-request is provided by the Api Testing MCP server (naveen-automation/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
