WHAT IT DOES

What append_project_fact does on Enhanced Knowledge Graph Memory Server

AI agents use append_project_fact 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 append_project_fact is rated Medium

This tool writes data by appending a fact to a project context record. It creates or modifies data reversibly — facts can be removed or overwritten. Auto-creation on first call and deduplication are write operations with no destructive, financial, or execution implications. Severity is low since it only adds structured knowledge graph entries.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs append_project_fact 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 append_project_fact, this is the rule to start with:

append_project_fact Rate-limited

append_project_fact 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.

What does the append_project_fact tool do? +

v2.1.0 \u2014 Append one fact to a project context (auto-creates the record on first call; dedups). 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 append_project_fact? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for append_project_fact: 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 append_project_fact? +

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

Can I rate-limit append_project_fact? +

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