Enumerate Tool nodes detected by the tools ingestion phase, optionally filtered by name substring. Returns name, file_path, description, and the parsed input schema (JSON-decoded when available, raw string when unparseable, null when unset). Read-only.
AI agents call tool_map to retrieve information from OpenCodeHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a query/enumeration tool that returns information about tools in the system. The explicit 'Read-only' designation and the nature of the operation (enumerating and filtering existing data) clearly place it in the Read category. The severity is low because it only exposes metadata about tools without providing direct access to sensitive operations or data modification capabilities.
From the tool's definition Tool is explicitly described as 'Read-only' and 'Enumerate Tool nodes detected by the tools ingestion phase'. It retrieves metadata about detected tools (name, file_path, description, input schema) without modifying any data.
Attacks that exploit this kind of access
Enumerate Tool nodes detected by the tools ingestion phase, optionally filtered by name substring. Returns name, file_path, description, and the parsed input schema (JSON-decoded when available, raw string when unparseable, null when unset). Read-only. It is categorised as a Read tool in the OpenCodeHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenCodeHub MCP Server MCP server in PolicyLayer and add a rule for tool_map: 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 OpenCodeHub MCP Server. Nothing to install.
tool_map 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 tool_map 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 tool_map. 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.
tool_map is provided by the OpenCodeHub MCP Server MCP server (theagenticguy/opencodehub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
