Most developer tooling work still happens through a UI a human drives. Raigo MCP server moves it into the conversation instead. The .raigo format is the open-source contribution. It is free to use, implement, extend, and build on. Anyone can write a .raigo file, build a compiler that reads it, or build an engine that enforces it. The format is not tied to any.
The server publishes 14 tools. What each one is for:
framework — "HIPAA"Model — How It RunsCompiler — CLI tool, zero infrastructureTarget — Output Formatclaude — XML System Promptchatgpt — Markdown Instructionsn8n — JSON System Promptopenclaw — JSON Constraint Schemalovable — Markdown Knowledge Blockgemini — JSON System Instructionperplexity — Markdown System Promptcopilot — JSON Policy ObjectBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Raigo's toolset — framework, Model, Compiler and 11 more — is a fair guide to whether it matches your workflow. It is maintained by periculolimited; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
