Daimonos

What is Daimonos?

Daimonos is a single Rust binary MCP server that reduces token usage and cost for AI coding agents by replacing built-in file, search, exec, and git tools with structured equivalents that return compact JSON instead of raw terminal output.

How to use Daimonos?

Download a pre-built binary for your platform and configure it as an MCP server with any compatible tool (Cursor, GitHub Copilot, Claude Code, Windsurf, Cline, Gemini CLI, Zed, etc.). No additional dependencies are required.

Key features of Daimonos

• Native tool plugins for git, cargo, gh, and docker with structured JSON output
• Semantic output filtering — test runners return summary + failures only
• Read deduplication — re-reading an unchanged file returns {"unchanged":true}
• Batch operations – multiple tools in a single round trip
• Workspace snapshots – checkpoint before risky edits, rollback on failure
• Token analytics with cross-session history

Use cases of Daimonos

• Reducing token consumption and API costs in agentic coding workflows
• Speeding up task completion through compact, structured tool responses
• Safely experimenting with code using workspace snapshots and rollback
• Combining multiple tool calls into a single Starlark script for efficiency

FAQ from Daimonos

Which MCP tools is Daimonos compatible with?

Daimonos works with Cursor, GitHub Copilot, Claude Code, Windsurf, Cline, Gemini CLI, Zed, and any MCP‑compatible tool.

How much can it reduce token usage and cost?

Benchmarks show 20–45% output token savings, 14–18% total cost reduction, and 16% faster task completion.

What are the runtime requirements?

Daimonos is a single Rust binary with no dependencies. Pre‑built binaries are provided for supported platforms.

How does read deduplication work?

If an agent re‑reads a file that has not changed since the last request, Daimonos returns {"unchanged":true} instead of the full file content, saving tokens and time.

What scripting capability does it offer?

Daimonos includes Starlark scripting, allowing you to bundle multiple tool calls into a single script executed in one round trip.
