Let Your AI Agent Post to Every Social Network
PostPeer ships a hosted MCP server and a typed SDK, so any agent framework (Claude, GPT, LangChain, CrewAI) can write, schedule, and publish to every major platform in a single call.
Building an agent that manages social media means wiring up Twitter, LinkedIn, Instagram, TikTok, YouTube, Pinterest, and Bluesky, each with its own API, OAuth flow, and content rules. PostPeer collapses all of that into one endpoint with a small, predictable surface area. Point your agent at the hosted MCP server or wrap a single REST call as a tool, and it can fan a post out to every connected platform, schedule ahead for review, and pull analytics back into its own context. The API is designed for the way agents actually work: small shapes, sane defaults, and guardrails so an over-eager agent cannot burn your quota.
Built For Agent Workflows
Hosted MCP, Zero Install
Point your client at https://mcp.postpeer.dev/mcp with a Bearer token and your agent gets 34 typed tools: post, schedule, list integrations, fetch analytics, manage profiles, BYOK apps, notifications, and more. Nothing to install, nothing to run locally.
Tool Calling for Any LLM
If your agent uses Anthropic tool use or OpenAI function calling, wrap the PostPeer REST endpoint as a single tool. The schema is small enough to fit comfortably in a system prompt, so the model can reason about it without extra context loading.
34 Typed Tools
Every public PostPeer endpoint is exposed as a typed MCP tool. Your agent can chain calls, list integrations, pick one, post, then fetch analytics, without ever touching raw HTTP.
Cross-Platform In One Call
An agent that picks the right platform for each piece of content can fan out to all of them in a single request. PostPeer normalizes character limits, media formats, and OAuth scopes per platform.
Guardrails and Feedback Loops
Idempotent, Reviewable Scheduling
Have the agent schedule for an hour out instead of publishing immediately. You get a queue you can review in the dashboard before anything goes live. Agents make mistakes, queues catch them.
Analytics For Learning
Pull impressions, likes, comments, shares, and engagement rate back into your agent so it can learn what works. One analytics endpoint, one credit per call, every connected platform.
Per-Day Credit Caps
Set a spending cap so a runaway agent cannot exhaust your quota. Failed posts do not count against you, and every scheduled post can be cancelled from the dashboard before it ships.
No Per-Platform Developer Apps
PostPeer handles every OAuth flow. Connect accounts once through PostPeer, and your agent uses the resulting account ID for the lifetime of the connection.
Key Benefits
Wrap PostPeer as an agent tool
Define one tool inside an Anthropic tool-use loop and let the model publish across platforms:
// Inside an Anthropic tool-use loop
const tools = [{
name: "post_to_social",
description: "Publish or schedule a post to one or more social platforms",
input_schema: {
type: "object",
properties: {
content: { type: "string" },
platforms: { type: "array", items: { type: "object" } },
scheduledFor: { type: "string" },
timezone: { type: "string" }
},
required: ["content", "platforms"]
}
}];
// When the model calls the tool:
await fetch("https://api.postpeer.dev/v1/posts", {
method: "POST",
headers: {
"x-access-key": process.env.POSTPEER_API_KEY,
"Content-Type": "application/json"
},
body: JSON.stringify(toolInput),
});PostPeer gives your agent a single, predictable interface to the entire social landscape. Wire it up once through the hosted MCP or a single REST tool, add scheduling and credit caps as guardrails, and feed analytics back in so the agent keeps getting better. You focus on the agent, PostPeer handles the platform complexity.
