create_record · API Registry MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_record does on API Registry MCP Server

AI agents use create_record to create or update resources in API Registry MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API Registry MCP Server environment.

WHY IT NEEDS A POLICY

Why create_record needs a policy

The tool creates/registers new data entries (API endpoints) in the registry, which is reversible through deletion or updates. This is a Write operation—data creation without irreversible destruction. Severity is medium because unauthorized API endpoint registration could enable injection attacks or unauthorized service connections, but the operation itself is not inherently destructive.

From the tool's definition Tool name 'create_record' indicates creation of data records. Sibling tools include 'update_record' and 'read_query', establishing a clear CRUD pattern.

create_record Rate-limited

create_record 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.
