THE RISK

Why match_concepts needs a policy

This is a query/matching tool that retrieves or correlates concepts from a knowledge base. It performs analysis and pattern matching without side effects, altering data, executing external commands, or committing resources. The 'ENTRY POINT' designation signals it is a read-only retrieval interface for initiating consultation workflows.

From the tool's definition Tool name 'match_concepts' and description 'Deterministically match a project description to knowledge' indicate a lookup/retrieval operation against a knowledge graph. No creation, modification, execution, or deletion of data is implied.

POLICY

How to control match_concepts

PolicyLayer is an MCP gateway — it sits between your AI agents and Iconsult MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for match_concepts:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "match_concepts": {}
  }
}

match_concepts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Iconsult MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about match_concepts

What does the match_concepts tool do? +

ENTRY POINT — Deterministically match a project description to knowledge. It is categorised as a Read tool in the Iconsult MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on match_concepts? +

Register the Iconsult MCP server in PolicyLayer and add a rule for match_concepts: 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 Iconsult MCP. Nothing to install.

What risk level is match_concepts? +

match_concepts is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit match_concepts? +

Yes. Add a rate_limit block to the match_concepts 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 match_concepts completely? +

Set action: deny in the PolicyLayer policy for match_concepts. 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 match_concepts? +

match_concepts is provided by the Iconsult MCP server (marcus-waldman/iconsult_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Iconsult MCP tool call.

Start from Iconsult MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
