WRITE: submit a candidate for promotion into the Waypath truth-kernel. Creates a new candidate row in the local SQLite review queue — it does NOT promote immediately. A human (or agent with explicit authority) must call waypath_review to accept or reject the candidate before it becomes queryable ...
AI agents use waypath_promote to create or update resources in Waypath — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Waypath environment.
An AI agent can call waypath_promote faster than any human can review — one bad instruction and it creates or modifies resources in Waypath by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
WRITE: submit a candidate for promotion into the Waypath truth-kernel. Creates a new candidate row in the local SQLite review queue — it does NOT promote immediately. A human (or agent with explicit authority) must call waypath_review to accept or reject the candidate before it becomes queryable by waypath_recall. Use when you want to persist a decision, preference, or fact; use waypath_review_queue to list pending candidates and waypath_review to act on them. It is categorised as a Write tool in the Waypath MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Waypath MCP server in PolicyLayer and add a rule for waypath_promote: 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 Waypath. Nothing to install.
waypath_promote is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the waypath_promote 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 waypath_promote. 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.
waypath_promote is provided by the Waypath MCP server (thestack-ai/waypath). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
