Etch is a signed audit chain for AI agent decisions, offline-verifiable against pinned public keys. This repository provides the MCP integration surface for the hosted Etch service, carrying MCP registry metadata (e.g., server.json, glama.json) and per-client integration materials.
Verifying AI agent decision trails using a pinned public-key set
Integrating the hosted Etch service through an MCP surface
⚡ Developer Benefits
Offline-verifiable audit evidence
MCP integration surface that includes registry metadata for discovery
⚠️ Limitations
The provided repository data indicates it carries only registry metadata and per-client integration components; detailed MCP tools and behaviors are not described here.
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.

code
curl -X POST https://etch.systems/v1/your-project
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.
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.

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.
