Retrieve a single post by ID with optional field expansions
AI agents call getSinglePost to retrieve information from X Com MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about a single post without modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk of misuse—the worst outcome would be unauthorized information disclosure if access controls were absent, but the tool itself performs no destructive or state-altering actions.
From the tool's definition Tool name 'getSinglePost' and description 'Retrieve a single post by ID with optional field expansions' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access getSinglePost gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and X Com MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getSinglePost:
{
"version": "1",
"default": "deny",
"tools": {
"getSinglePost": {}
}
}getSinglePost is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve a single post by ID with optional field expansions. It is categorised as a Read tool in the X Com MCP Server MCP Server, which means it retrieves data without modifying state.
Register the X Com MCP Server MCP server in PolicyLayer and add a rule for getSinglePost: 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 Com MCP Server. Nothing to install.
getSinglePost 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 getSinglePost 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 getSinglePost. 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.
getSinglePost is provided by the X Com MCP Server MCP server (tiovikram/x.com-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from X Com MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
