v1.8: Fetch detailed content of a specific ChromaDB chunk by ID.
AI agents call fetch_chunk_detail to retrieve information from Code Intelligence 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 content from a ChromaDB chunk—a read-only query operation. There are no side effects, no data modification, no code execution, and no destructive actions. The blast radius of misuse is minimal; an agent could retrieve unintended code chunks but cannot alter or delete data or trigger external operations. This is a classic Read category tool.
From the tool's definition Tool name 'fetch_chunk_detail' and description 'Fetch detailed content of a specific ChromaDB chunk by ID' indicate retrieval of existing data without modification or deletion. The verb 'Fetch' is a read operation.
Attacks that exploit this kind of access
v1.8: Fetch detailed content of a specific ChromaDB chunk by ID. It is categorised as a Read tool in the Code Intelligence MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code Intelligence MCP Server MCP server in PolicyLayer and add a rule for fetch_chunk_detail: 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 Code Intelligence MCP Server. Nothing to install.
fetch_chunk_detail 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 fetch_chunk_detail 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 fetch_chunk_detail. 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.
fetch_chunk_detail is provided by the Code Intelligence MCP Server MCP server (tech-spoke/llm-helper). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
