What prompt.assess_relevance does on ContextForge MCP Gateway
AI agents call prompt.assess_relevance to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why prompt.assess_relevance is rated Low
This tool retrieves and processes data (embeddings and similarity metrics) without modifying, deleting, or executing code. It is purely an analytical read operation that assesses semantic similarity between inputs and outputs. No data is created, destroyed, or irreversibly changed.
From the tool's definition Tool 'prompt.assess_relevance' measures semantic alignment using embeddings—a comparison/analysis operation with no state changes, deletions, or external side effects.
Attacks that exploit this kind of access
The rule that runs prompt.assess_relevance safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ContextForge MCP Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For prompt.assess_relevance, this is the rule to start with:
prompt.assess_relevance is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every prompt.assess_relevance call is checked against it from then on.
Questions about prompt.assess_relevance
