AI agents use waypath_recall 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_recall 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
Read-only hybrid search over the local Waypath SQLite memory store. Runs FTS5 lexical search fused with graph-aware Reciprocal Rank Fusion (RRF) across truth-kernel and archive tables and returns ranked entries with source, score, and snippet. Use before answering any question that may depend on prior decisions, preferences, or project facts; call this instead of waypath_graph_query when you have a free-text query rather than a known entity id. Does not write to the database and does not hit the network. 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_recall: 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_recall 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_recall 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_recall. 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_recall 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.
