AI agents call knitbrain_propose_agents to retrieve information from Knitbrain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only proposes/detects agent configurations from an existing knowledge graph — it does not create or modify anything. Creation is explicitly deferred to a separate tool (knitbrain_create_agent), making this a read/query operation with no side effects.
From the tool's definition Auto-detect project-specific agent proposals from the knowledge graph (domains + guardrails). Review/edit, then create with knitbrain_create_agent.
Attacks that exploit this kind of access
Auto-detect project-specific agent proposals from the knowledge graph (domains + guardrails). Review/edit, then create with knitbrain_create_agent. It is categorised as a Read tool in the Knitbrain MCP Server, which means it retrieves data without modifying state.
Register the Knitbrain MCP server in PolicyLayer and add a rule for knitbrain_propose_agents: 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 Knitbrain. Nothing to install.
knitbrain_propose_agents is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the knitbrain_propose_agents 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.
Set action: deny in the PolicyLayer policy for knitbrain_propose_agents. 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.
knitbrain_propose_agents is provided by the Knitbrain MCP server (pdgit12/knitbrain). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
