AI agents call recall to retrieve information from THOUGHT without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the tool name 'recall' combined with the server's purpose (persistent memory with querying/browsing capabilities) and the presence of explicit read verbs among siblings (browse_topic, list_topics, query, scan) strongly indicates this retrieves stored information without side effects. No evidence suggests write, deletion, or execution capabilities.
From the tool's definition Tool name 'recall' on a memory server with sibling tools that include 'query', 'browse_topic', and 'list_topics' strongly indicates data retrieval.
Attacks that exploit this kind of access
recall. It is categorised as a Read tool in the THOUGHT MCP Server, which means it retrieves data without modifying state.
Register the THOUGHT MCP server in PolicyLayer and add a rule for 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 THOUGHT. Nothing to install.
recall 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 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 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.
recall is provided by the THOUGHT MCP server (rnbbarrett/thought-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
recall is one line of THOUGHT's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
