add_text_to_index · ElasticMind- MCP: Risk & Policy

WHAT IT DOES

What add_text_to_index does on ElasticMind-MCP

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

WHY IT NEEDS A POLICY

Why add_text_to_index needs a policy

This tool creates or appends new text data to an Elasticsearch index, which is a reversible write operation. While the description is empty, the name and server context make the intent clear. Severity is medium because uncontrolled text ingestion could pollute the knowledge base or introduce misleading information, but the operation itself is reversible via deletion or re-indexing.

From the tool's definition Tool name 'add_text_to_index' combined with server description stating it 'ingest new files, and dynamically update content' indicates this tool modifies indexed data by adding text entries to an Elasticsearch index.
