Request

POST

# Install the MCP (run once)
claude mcp add postpeer_mcp_api \
  --env POSTPEER_API_KEY="your-api-key" \
  -- npx -y postpeer-mcp

# Then in Claude Code, just talk:
> "post HI from postpeer on my twitter"

# Claude runs (under the hood):
async function run(client) {
  const res = await client.posts.create({
    content: "HI from postpeer",
    publishNow: true,
    platforms: [{ accountId: "<id>", platform: "twitter" }],
  });
  return res;
}

Post to Social Media From Your Terminal

PostPeer's MCP is built specifically for terminal-first workflows. Tutorial: /blog/automate-social-media-with-claude-code-and-ai-agents.

One Command to Install

Run `claude mcp add postpeer_mcp_api --env POSTPEER_API_KEY=... -- npx -y postpeer-mcp` and you're done. The MCP shows up as `mcp__postpeer_mcp_apiexecute` and `mcppostpeer_mcp_api__search_docs` in your next session.

Talk, Don't Code

Tell Claude 'post HI from postpeer on my twitter' and it figures out the integration ID, calls the API, and returns the live URL. No copy-pasting account IDs or remembering endpoint shapes.

Schedule From the CLI

'Schedule a LinkedIn post for tomorrow at 9am ET' becomes a real queued post in PostPeer. Review and cancel from the dashboard before it ships.

Cross-Post In One Sentence

'Post this changelog summary to Twitter, LinkedIn, and Bluesky.' One sentence, one API call, three live posts. Claude handles the platform array; PostPeer handles the platform differences.

Built-In Doc Search

The MCP exposes a `search_docs` tool, so Claude can look up SDK methods, parameter shapes, and platform-specific options without you context-loading the docs into the conversation.

Composable With Other MCPs

Combine PostPeer with your GitHub, Linear, or analytics MCPs to build genuinely useful workflows. 'Read yesterday's merged PRs and draft a thread about the highlights', all in one Claude Code session.
