What you can do with Lemmy

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Lemmy API rate limits

180 requests per minute
Bursts of up to 180 requests

Rate limits are instance-configurable. Default limits: 6 actions per 600 seconds for posting, 600 requests per 600 seconds for messages. Check instance documentation for specific limits.

These are the limits Lemmy documents, not ones LiveContext measured. They can change and often depend on your plan, so check the Lemmy documentation for current values.

Use Lemmy from Claude Code, Cursor or Codex

Connect Lemmy in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Lemmy operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
