List all connected social media accounts on PostEverywhere. Returns account IDs, platform names, usernames, and health status (whether each account can currently post). Use this to see which platforms are available before creating a post.
AI agents call list_accounts to retrieve information from Posteverywhere without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing account metadata without creating, modifying, or deleting any data. It is purely informational and serves to enumerate available accounts before other operations. The blast radius of misuse is minimal—an agent could enumerate accounts but cannot take action with them without using other tools. This is a classic Read category operation.
From the tool's definition Tool description explicitly states 'List all connected social media accounts' and 'Returns account IDs, platform names, usernames, and health status'.

List all connected social media accounts on PostEverywhere. Returns account IDs, platform names, usernames, and health status (whether each account can currently post). Use this to see which platforms are available before creating a post. It is categorised as a Read tool in the Posteverywhere MCP Server, which means it retrieves data without modifying state.
Register the Posteverywhere MCP server in PolicyLayer and add a rule for list_accounts: 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 Posteverywhere. Nothing to install.
list_accounts 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 list_accounts 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 list_accounts. 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.
list_accounts is provided by the Posteverywhere MCP server (posteverywhere/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
