Runs local semantic search over analyzed archived posts using the optional analysis layer.
AI agents call archive.posts.semantic_search to retrieve information from X Archive Daemon without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from a local SQLite database without creating, modifying, deleting, or executing external operations. It performs semantic search (a read operation) over existing archived posts. Even though it uses embeddings and analysis, the core function is data retrieval with no side effects. No financial, destructive, or code execution capability is evident.
From the tool's definition Tool description states it 'Runs local semantic search over analyzed archived posts' — a query operation with no modification or deletion of data. The verb 'search' and context of querying an archive database indicate retrieval only.
Attacks that exploit this kind of access
Runs local semantic search over analyzed archived posts using the optional analysis layer. It is categorised as a Read tool in the X Archive Daemon MCP Server, which means it retrieves data without modifying state.
Register the X Archive Daemon MCP server in PolicyLayer and add a rule for archive.posts.semantic_search: 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 X Archive Daemon. Nothing to install.
archive.posts.semantic_search 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 archive.posts.semantic_search 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 archive.posts.semantic_search. 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.
archive.posts.semantic_search is provided by the X Archive Daemon MCP server (menesekinci/x-archive-daemon). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
