What we handle

Five guarantees.
Zero DevOps.

We own the full lifecycle so your protocol stays agent-readable — through every API change, agent framework update, and registry migration.

01
Host
Dedicated subdomain at {id}.mcp.junct.dev. Streamable HTTP, stateless, always-on.
02
Maintain
Spec changes upstream? We detect, regenerate, and redeploy. Your server never goes stale.
03
Distribute
Auto-submitted to PulseMCP, GitHub Directory, Coinbase AgentKit, and more on deploy.
04
Monitor
Live validation against the spec on every call. Drift, failures, and coverage gaps surfaced instantly.
05
Upgrade
New MCP transport? New agent framework? We upgrade the server layer. Zero migration work.

How it works

Spec in.
MCP server out.

  • 01
    Upload your spec
    OpenAPI JSON, contract ABI, or llms.txt. Paste a URL or drop the file. Multiple files merge into one server.
  • 02
    Parse & classify
    Every operationId becomes a tool. 1:1. No phantom tools, no injected patterns. Domain classifier enriches descriptions only.
  • 03
    Generate & validate
    TypeScript MCP server generated and statically validated against the spec. Fails loudly if coverage is wrong.
  • 04
    Deploy & register
    Hosted at your subdomain. Auto-submitted to PulseMCP, GitHub Directory, and the agent ecosystem.
