Outpost — Social API for AI Agents

2026 — ongoing

2026

Post to X, LinkedIn, Instagram, Reddit, Bluesky, and Threads from any AI agent with a single API call, or straight from Claude Desktop and Cursor through its MCP server.

Outpost is open source and self-hostable with one Docker Compose command. A hosted API runs at outpost.hibernyte.com.

One publish endpoint for six social platforms, plus MCP

One endpoint, every platform

Every platform takes the same request shape, so an agent learns one call instead of six SDKs:

curl -X POST https://outpost.hibernyte.com/api/v1/publish \
  -H "X-API-Key: sa_xxx" \
  -H "Content-Type: application/json" \
  -d '{"platform":"x","accountId":"<id>","content":{"text":"Hello from Outpost!"}}'

Built for agents, not dashboards

Every failure returns a code and an agentHint, so the model knows what to do next instead of guessing from an HTTP status.
An MCP server ships in the repo and works natively in Claude Desktop, Cursor, and any MCP-compatible agent.
Multi-tenant OAuth: each organization connects its own social accounts, with credentials isolated per org instead of shared.

Stack

NestJS 11 in TypeScript, PostgreSQL 16 through Prisma, Redis 7, API key auth, and an MCP server over stdio, all in one monorepo with the landing page. Production deploys from main through Coolify.
