WHAT IT DOES

What add_heuristic does on Enhanced Knowledge Graph Memory Server

AI agents use add_heuristic to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment.

RISK

Why add_heuristic is rated Medium

An AI agent can call add_heuristic faster than any human can review: one bad instruction and it creates or modifies resources in Enhanced Knowledge Graph Memory Server by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_heuristic safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_heuristic, this is the rule to start with:

add_heuristic Rate-limited

add_heuristic stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about add_heuristic

What does the add_heuristic tool do? +

v2.1.0 \u2014 Register a new condition\u2192action heuristic. Storage-backed; default confidence 0.5. Pass an explicit content-addressed id (e.g. h_<sha256(condition|action)>) for caller-managed idempotency. It is categorised as a Write tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_heuristic? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for add_heuristic: 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 Enhanced Knowledge Graph Memory Server. Nothing to install.

What risk level is add_heuristic? +

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

Can I rate-limit add_heuristic? +

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

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

add_heuristic is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
