WHAT IT DOES

What query-knowledge-graph does on CodeAnalysis MCP Server

AI agents call query-knowledge-graph to retrieve information from CodeAnalysis MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why query-knowledge-graph is rated Low

The tool name and context indicate read-only querying of a knowledge graph data structure. No description is provided, which slightly lowers confidence, but the 'query' verb and sibling tools strongly suggest a retrieval operation with no side effects. The knowledge graph appears to be built separately ('build-knowledge-graph'), so this tool likely only accesses it.

From the tool's definition Tool name 'query-knowledge-graph' contains 'query', which typically performs data retrieval without modification. The sibling 'build-knowledge-graph' suggests this tool queries an already-constructed graph rather than modifying it.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs query-knowledge-graph safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CodeAnalysis MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For query-knowledge-graph, this is the rule to start with:

query-knowledge-graph Allowed

query-knowledge-graph is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "query-knowledge-graph": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CodeAnalysis MCP Server, apply this rule, and every query-knowledge-graph call is checked against it from then on.
