Resolves a public X account by username or userId.
AI agents call sources.accounts.resolve 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 performs a straightforward query to resolve public X account information. It retrieves data without modifying, creating, deleting, or executing arbitrary operations. The input (username or userId) is constrained to account resolution rather than code execution or destructive actions. Public account resolution is a fundamental read operation with minimal security risk.
From the tool's definition Tool name 'sources.accounts.resolve' and description 'Resolves a public X account by username or userId' indicate a lookup/retrieval operation on public account data with no modification, deletion, or external side effects.
Attacks that exploit this kind of access
Resolves a public X account by username or userId. 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 sources.accounts.resolve: 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.
sources.accounts.resolve 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 sources.accounts.resolve 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 sources.accounts.resolve. 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.
sources.accounts.resolve 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.
