index · Mcp Recall Md MCP: Risk & Policy

WHAT IT DOES

What index does on Mcp Recall Md

AI agents use index to create or update resources in Mcp Recall Md — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Recall Md environment.

WHY IT NEEDS A POLICY

Why index needs a policy

The tool creates or updates an indexed article entry, and explicitly replaces existing content with the same key. This is a write/update operation — reversible in principle (you could re-index the old content), but it does overwrite existing data. It does not delete records permanently nor execute code, so Write is the most appropriate category.

From the tool's definition 'Index a knowledge base article. Replaces any existing article with the same key.'

Verdict

index Rate-limited

index 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.
