WHAT IT DOES

What set_dependency_map does on Mcp Coordinator

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

WHY IT NEEDS A POLICY

Why set_dependency_map needs a policy

This tool creates or modifies the dependency graph used by the coordination system. While not destructive (the operation is reversible by loading a different map), it goes beyond reading data—it actively establishes or updates a data structure that influences system behavior.

From the tool's definition Tool is described as 'Load module dependency graph' which involves storing or modifying dependency relationship data.

FAQ

Questions about set_dependency_map

What does the set_dependency_map tool do? +

Load module dependency graph. It is categorised as a Write tool in the Mcp Coordinator MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_dependency_map? +

Register the Mcp Coordinator MCP server in PolicyLayer and add a rule for set_dependency_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 Mcp Coordinator. Nothing to install.

What risk level is set_dependency_map? +

set_dependency_map is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_dependency_map? +

Yes. Add a rate_limit block to the set_dependency_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.

How do I block set_dependency_map completely? +

Set action: deny in the PolicyLayer policy for set_dependency_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.

What MCP server provides set_dependency_map? +

set_dependency_map is provided by the Mcp Coordinator MCP server (swoofer/mcp-coordinator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
