WHAT IT DOES

What mcp_create_text_index does on Mongo-MCP

AI agents use mcp_create_text_index to create or update resources in Mongo-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mongo-MCP environment.

RISK

Why mcp_create_text_index is rated Medium

Creating a text index modifies the database schema and metadata by adding an index structure. This is a reversible Write operation (indexes can be dropped via 'mcp_drop_collection' or explicit index deletion). It does not delete data, execute arbitrary code, or move money.

From the tool's definition Tool name 'mcp_create_text_index' indicates index creation on MongoDB. Sibling tools include 'mcp_create_index' and 'mcp_create_compound_index', confirming this is an index management operation. Tool description is empty, limiting specificity.

RECOMMENDED RULE

The rule that runs mcp_create_text_index safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mongo-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_create_text_index, this is the rule to start with:

mcp_create_text_index Rate-limited

mcp_create_text_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.

The button opens the PolicyLayer dashboard: create your workspace, connect Mongo-MCP, apply this rule, and every mcp_create_text_index call is checked against it from then on.
