Tool Catalog Compiler

toolc

English | [Русский](README.ru.md)

[](LICENSE)     

Compile noisy OpenAPI and MCP tool surfaces into one smaller governed runtime surface for LLM agents.

Validated today with real OpenRouter model runs, real saved benchmark artifacts, and a live OpenAPI invoke check.

Best fit today:

• VS Code users with too many MCP servers
• OpenAPI or MCP-heavy agent stacks
• teams that want less exposed tool surface without a platform rewrite

Install

Two supported paths for `v1.0.0`:

1. download a prebuilt archive from GitHub Releases
2. install from source with Go

go install github.com/aak204/Tool-Catalog-Compiler/cmd/toolc@v1.0.0

After the `v1.0.0` tag is published as the latest tag, this also works:

go install github.com/aak204/Tool-Catalog-Compiler/cmd/toolc@latest

Release assets for `v1.0.0`:

• toolc_v1.0.0_windows_amd64.zip
• toolc_v1.0.0_linux_amd64.tar.gz
• toolc_v1.0.0_linux_arm64.tar.gz
• toolc_v1.0.0_darwin_amd64.tar.gz
• toolc_v1.0.0_darwin_arm64.tar.gz

VS Code Quickstart

If you already use MCP in VS Code, start here.

`toolc` can take the MCP config you already use, compile it into one smaller controlled surface, and become the single MCP server your agent sees.

Start here:

1. build toolc
2. optimize your existing MCP config
3. point your extension at the emitted config
4. run one toolc mcp-serve surfac
