MCP Server for Social Media: Manage Every DM and Post From Your AI Assistant

@crmsolid/mcp-server is an MCP server for social media. It gives Claude Desktop, Claude Code, Cursor, ChatGPT and any other Model Context Protocol client typed access to your social DM inbox and your posting calendar across 12 platforms, so you can triage messages, draft replies, schedule posts and pull stats without opening a single dashboard.

Quickstart

Add this to your MCP client config, restart the client, and ask it to list your social accounts. Nothing to install: npx fetches the package on first run.

{
  "mcpServers": {
    "crmsolid": {
      "command": "npx",
      "args": ["-y", "@crmsolid/mcp-server"],
      "env": { "CRMSOLID_API_KEY": "csk_live_..." }
    }
  }
}

Create the key at app.crmsolid.com/settings/developers. Config file locations per client:

Then say, in the client: List my connected social accounts. If you get a table back, you are done. If you do not, jump to Troubleshooting.

What you can ask for once it is connected

These are ordinary sentences, not commands. The client picks the tools.

Summarise my social inbox and show the conversations waiting longest for a reply.
Draft a friendly reply to the Instagram DM from Dilara about the 12 month plan.
Anything mentioning a refund today? Open a task for each one and assign the contact.
Plan five posts for next week from what we shipped, and show me the table before you schedule any of them.
Move Thursday's LinkedIn post to Friday 09:00 Europe/Istanbul.
How did last month's posts do compared with the month before?

The panel behind the tools

The server is not a separate copy of your data. It reads and writes the same social inbox and the same posting calendar you see in CRM Solid, so a conversation you triage from Claude is already triaged when you open the panel, and a post your assistant queues shows up in the calendar with everything else.

Both screens come from the live demo at demo.crmsolid.com, which is read only and needs no account.

Supported platforms

Instagram, Facebook, X (Twitter), LinkedIn, TikTok, YouTube, Threads, Pinterest, Reddit, Bluesky, Telegram and WhatsApp. One inbox, one calendar, one tool surface. A recipe written against Instagram works against LinkedIn without changes, though per platform messaging windows and policies still apply.

Tool reference

Thirteen social tools ship in this release: seven for the DM inbox, six for posts. They sit alongside 49 CRM tools (contacts, deals, tasks, email, finance, analytics, sequences, pipelines, jobs, webhooks, agents) on the same server, which is the point: a DM that never becomes a contact record is a DM you will lose.

Social inbox

Social posts

Full arguments, example calls and example responses for every tool: docs/tools-reference.md.

The publishing rule. crm_schedule_social_post requires scheduledAt unless you pass publishNow: true explicitly. Leave both out and the call is rejected with scheduledAt is required unless publishNow is true. An assistant that misunderstands you gets an error, never a surprise post. Two more guards sit behind it: each target account's daily post limit is checked before anything is written, and a post that already went out on the platform cannot be cancelled or deleted through the API.

Resources

Attach these when you want the model to read state without spending a tool call.

Configuration reference

A flag beats the matching environment variable. Two useful profiles:

// Content scheduling only, on a machine that must never touch the inbox.
{
  "mcpServers": {
    "crmsolid": {
      "command": "npx",
      "args": ["-y", "@crmsolid/mcp-server", "--tools", "posts"],
      "env": { "CRMSOLID_API_KEY": "csk_live_..." }
    }
  }
}

// Read only, for a shared laptop or a demo.
{
  "mcpServers": {
    "crmsolid": {
      "command": "npx",
      "args": ["-y", "@crmsolid/mcp-server", "--read-only"],
      "env": { "CRMSOLID_API_KEY": "csk_live_..." }
    }
  }
}

Requires Node 20 or newer. The package is ESM, ships a crmsolid-mcp binary, and speaks MCP over stdio.
