ckanthony/Chisel
🪛 Rust powered precision file tools for AI agents thats minimize context use: patch-based edits, kernel-enforced path confinement. Dramatically fewer tokens than naive read/write. MCP Server or embeddable, bring your own MCP (Rust, Python, Nodejs). Come with Skills.md (npx skills add ckanthony/Chisel)
Platform-specific configuration:
{
"mcpServers": {
"Chisel": {
"command": "npx",
"args": [
"-y",
"Chisel"
]
}
}
}Add the config above to .claude/settings.json under the mcpServers key.

🪛 Rust powered precision file operations for agents. Unix-native tools, minimal context footprint, strict path confinement: use directly with Chisel MCP or bring your own MCP, embeddable in any MCP server in Rust, Python, Nodejs.

> Agent skill included — `skills/chisel/SKILL.md` teaches agents how to use Chisel at maximum efficiency. Install with: npx skills add ckanthony/Chisel
> Security hardened — Verified properties across two layers: the MCP server (chisel) and the portable core library (chisel-core). See the Security model section for the full breakdown.
