**Etch is a signed audit chain for AI agent decisions, offline-verifiable against pinned public keys.**
This repository is the MCP integration surface for Etch, the hosted service. It carries only:
- The MCP registry metadata (server.json, glama.json)
- Per-client integration examples for Claude Code / Cursor / Continue / Cline / Codex
- Documentation for attaching an MCP-compliant client to Etch
The hosted Etch service source is proprietary and lives in a separate repository. Nothing in this repository is required to be inspected or modified in order to use Etch.

The response returns a bearer token, an MCP endpoint URL, and an anonymous project id. Point any MCP-compliant client at https://etch.systems/mcp with the token. Anonymous projects carry 500 signed events over 14 days; convert to a persistent project any time to keep the chain forever.
Full walk-through: etch.systems/docs/quickstart.
Per-client config
Claude Code
~/.claude/settings.json:
Cursor
~/.cursor/mcp.json (or .cursor/mcp.json at the project root):
Continue
~/.continue/config.yaml:
Cline (VS Code)
~/.config/Cline/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json:
Codex CLI
~/.codex/config.toml:
Per-client documentation with current config file locations is kept up-to-date at etch.systems/docs/mcp-clients.
Verify
Every event Etch signs is verifiable offline against pinned public keys with the OSS reference verifier. Auditors pin fingerprints once at pilot onboarding; every past epoch is verifiable indefinitely without contacting Etch.

What Etch is NOT
- Not a media-provenance envelope (that lane is C2PA and SPIF). Etch signs decisions, not content. Comparison: etch.systems/vs/c2pa.
- Not a transparency log (that lane is Sigstore Rekor). Etch is a per-project chain that anchors epochs on Rekor. Comparison: etch.systems/vs/sigstore-rekor.
- Not a watermarking system. Etch records who reviewed an output and what they applied, not whether a specific model touched the text.
