Social media posting MCP server for AI agents
Postwire is a social media posting backend for AI agents that gives Claude Code, Cursor or Codex a documented set of endpoints to publish and track posts.
What exists today
Today Postwire connects to AI tools through its REST API plus a generated skill: the AI access page creates a SKILL.md for Claude Code, a rules file for Cursor and an AGENTS.md section for Codex, each listing every endpoint and reading your key from an environment variable.
That covers the same ground most agents use an MCP server for: send a package, read variants, approve, and check results.
Where MCP fits
A native MCP server is planned as part of the Maker plan alongside API access. It is not shipped yet, and this page will say so until it is.
If you need an MCP server for posting right now, check whether the tool you use offers one; otherwise the generated skill is the supported path.
Frequently asked
- Does Postwire have an MCP server?
- Not yet. MCP is planned for the Maker plan; today agents use the REST API through a generated skill for Claude Code, Cursor or Codex.
- Is the generated skill safe to share?
- The skill text never contains your key; it reads it from an environment variable you set once in your terminal.
- What can the agent not do?
- An API key cannot change billing, e-mail or other accounts, and extension-only actions use a separate, narrower key.
