List all supported file types and extensions for batch processing.
AI agents call list_file_types to retrieve information from ChromaDB Local MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about supported file types. It performs no modification, deletion, execution, or financial operations. It is a straightforward informational query with no blast radius if invoked by an AI agent.
From the tool's definition Tool name 'list_file_types' and description 'List all supported file types and extensions for batch processing' indicate a query operation that retrieves configuration/metadata without side effects.

List all supported file types and extensions for batch processing. It is categorised as a Read tool in the ChromaDB Local MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ChromaDB Local MCP Server MCP server in PolicyLayer and add a rule for list_file_types: 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 ChromaDB Local MCP Server. Nothing to install.
list_file_types is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_file_types 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.
Set action: deny in the PolicyLayer policy for list_file_types. 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.
list_file_types is provided by the ChromaDB Local MCP Server MCP server (vespo92/chromadblocal-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
