Social Champ MCP server

A Model Context Protocol (MCP) server for the Social Champ platform. It exposes the full Social Champ tool catalog to MCP-compatible AI clients such as Claude Desktop, Claude Code, and Cursor: scheduling and managing posts, managing connected channels and workspaces, labels, queues, recycling, shareable calendars, agency approval workflows, and the AI content wizard.

Tools

This server mirrors the live Social Champ MCP tool catalog. Channels are connected social profiles; workspaces group channels and shareable calendars. The tool definitions are generated from tools.schema.json, a snapshot of the live server's catalog, so the full set of tools, argument names, and descriptions stays in parity with the hosted server.

Tools are grouped by domain:

• Posts: create, update, delete, bulk schedule, browse, reorder the queue, set Instagram first comment.

• Channels: list, filter, fetch one, location search.

• Workspaces: list.

• Calendars: view options, in-app URL, shareable calendar create, list, update, delete.

• Queue: pause, resume, clear.

• Labels: list, create, apply, remove, bulk apply.

• Recycling: list collections, recycle a post.

• Agency workflows: list pending approvals, approve, reject, remind approvers, bulk delete.

• AI wizard: generate a post, suggest hashtags, rewrite, generate images.

Each tool is annotated with ToolAnnotations so clients can apply the right confirmation behavior. Read-only tools carry readOnlyHint=True; destructive tools (delete_post, delete_shareable_calendar, bulk_delete, queue_clear) carry destructiveHint=True. Agency tools require the caller token to also carry the manage_team scope; this is noted in each tool's description.

For the full per-tool list with required arguments and scopes, see tools.schema.json here, or api/mcp/IMPLEMENTED.md in the auth repo.

Requirements

• Python 3.10 or newer.

• A Social Champ API key or OAuth2 access token. Both are sent as a Bearer token. OAuth2 scopes used by the published tools are read_profile and manage_post; the agency tools (approvals, reminders, bulk delete) also need manage_team.

Install

With uv, as a command on your PATH:

uv tool install socialchamp-mcp

If your shell then cannot find socialchamp-mcp, run uv tool update-shell and open a new terminal. To run it without installing, use uvx socialchamp-mcp wherever this README says socialchamp-mcp.

With pip:

pip install socialchamp-mcp

From source:

git clone https://github.com/socialchamp/socialchamp-mcp.git
cd socialchamp-mcp
pip install -e ".[dev]"

Configuration

Set configuration through environment variables.

The server reads only the environment; it does not load a .env file itself. For local use, put the variables in a .env file (in a source checkout, copy .env.example; otherwise create it with a line SOCIALCHAMP_API_KEY=... in an editor), make it readable only by you, and load it into your shell before starting the server:

chmod 600 .env
set -a; . ./.env; set +a

Run unset SOCIALCHAMP_API_KEY when you are done. Never commit .env.

MCP client setup

Claude Desktop

Add the server to claude_desktop_config.json:

{
  "mcpServers": {
    "socialchamp": {
      "command": "socialchamp-mcp",
      "env": {
        "SOCIALCHAMP_API_KEY": "your-api-key"
      }
    }
  }
}

If the console script is not on your PATH, use "command": "python" with "args": ["-m", "socialchamp_mcp"].

Claude Code

The simplest way is the hosted server, with no API key: you sign in to Social Champ in your browser instead.

claude mcp add --scope user --transport http SocialChamp https://mcp.socialchamp.com/mcp

Then run /mcp in Claude Code, choose SocialChamp and sign in. --scope user makes the server available in every folder you open Claude Code in; without it, only in the folder where you ran the command. The sign-in grants read_profile and manage_post; approvals and other agency tools need manage_team, so use an API key that has it if you need those.

To run this package locally with an API key instead, read the key without showing it or saving it to your shell history:

printf 'Social Champ API key: '; read -rs SOCIALCHAMP_API_KEY; printf '\n'
claude mcp add --scope user SocialChamp --env SOCIALCHAMP_API_KEY="$SOCIALCHAMP_API_KEY" -- socialchamp-mcp
unset SOCIALCHAMP_API_KEY

With uvx, end the second line with -- uvx socialchamp-mcp instead. Claude Code keeps the key in its own settings (~/.claude.json), as it does for any server's environment, and the key is visible to other processes on the machine for the moment the command runs. On a shared machine, prefer the hosted sign-in.

Calendar pane for Claude Code

Using Claude Code? The Social Champ calendar mod adds a side pane on top of this server: week, month and day views, failed posts and approvals, drafts, and new posts written with Claude. It shows every change first and sends it only after you press Yes. It also asks you before Claude changes anything in Social Champ from chat.

claude plugin marketplace add SocialChamp/socialchamp-claude-mods
claude plugin install socialchamp-calendar@socialchamp-mods

It needs Claude Code 2.1.293 or later. Run /reload-plugins, then /socialchamp-calendar. The mod looks for this server under the name SocialChamp, as added above, so there is nothing to set. If you added it under another name, set that name once with /plugin configure socialchamp-calendar@socialchamp-mods. In auto mode, add the permission rules from the mod's README (mcp__<server name>__<tool>, spaces in the name as underscores) once the pane has opened.

Running over HTTP

The default transport is stdio, which is what Claude Desktop and Claude Code use. To run over HTTP instead, set SOCIALCHAMP_TRANSPORT:

printf 'Social Champ API key: '; read -rs SOCIALCHAMP_API_KEY; printf '\n'
export SOCIALCHAMP_API_KEY
SOCIALCHAMP_TRANSPORT=streamable-http socialchamp-mcp

sse is also supported. Point your client at the resulting HTTP endpoint.

Mapping to the real API

The tools forward to the hosted Social Champ MCP server over JSON-RPC. The live tools are implemented in the auth backend (api/mcp/handlers.ts) and reach champ through internal service routes that an external API key cannot call directly, so the only surface a user's token can reach for the full catalog is the hosted MCP server. src/socialchamp_mcp/client.py is the only file that makes HTTP calls: it speaks JSON-RPC 2.0 (initialize, tools/list, tools/call) to the endpoint in SOCIALCHAMP_API_BASE_URL.

src/socialchamp_mcp/server.py is generated from tools.schema.json, a snapshot of the live server's api/mcp/tools.ts. To refresh after the live catalog changes:

1. Re-export the snapshot from the auth repo into tools.schema.json (the live tools.ts array, as JSON).

2. Run python scripts/generate_server.py.

The base URL and Bearer authentication are confirmed from the Social Champ authentication guide.

Adding a tool

Tools are generated, not hand-written. Add the tool to the live api/mcp/tools.ts in the auth repo, refresh tools.schema.json, then run python scripts/generate_server.py. The generator maps each tool to a @mcp.tool function that forwards to call_tool, picks a ToolAnnotations preset (READ, WRITE, UPDATE, DESTRUCTIVE), and writes the docstring from the tool description. Update the classification sets in scripts/generate_server.py when adding a destructive or read-only tool.

See CONTRIBUTING.md for the full checklist.

Development

pip install -e ".[dev]"
pytest

To confirm the server starts over stdio:

SOCIALCHAMP_API_KEY=dummy SOCIALCHAMP_TIMEOUT=5 socialchamp-mcp

It waits for input on stdin rather than exiting. Stop it with Ctrl+C.

Security

• The API key is read from the environment and sent as a Bearer token. It is never logged or written to disk by this server.

• Keep your key in .env or your client's secret store. Never commit it, and never type it into a command line, where shell history keeps it. The .gitignore excludes .env. Signing in with OAuth (the hosted server) needs no key at all.

• Tools are annotated read-only, write, or destructive. Destructive tools (delete_post, delete_shareable_calendar, bulk_delete, queue_clear) carry destructiveHint=True so clients can confirm before running them.

• Agency tools require the caller token to carry the manage_team scope. Tokens without it cannot invoke them.

• Scope your token to only the permissions the tools need. If a token is exposed, rotate it in your Social Champ account.
