ChatGPT cannot connect Etch yet

Etch needs your own key to connect, but OpenAI’s help page only describes OAuth sign-in; there is no key option we could verify

Common questions

Is Etch safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (0.1.1) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

etch-mcp

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.

Try in 30 seconds, no signup

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.

Full walk-through: etch.systems/docs/quickstart.

Per-client config

Claude Code

~/.claude/settings.json:

"mcpServers": { "etch": { "url": "https://etch.systems/mcp", "headers": { "Authorization": "Bearer wm_YOUR_ANON_TOKEN" } } } }

Cursor

~/.cursor/mcp.json (or .cursor/mcp.json at the project root):

"mcpServers": { "etch": { "url": "https://etch.systems/mcp", "headers": { "Authorization": "Bearer wm_YOUR_ANON_TOKEN" } } } }

Continue

~/.continue/config.yaml:

mcpServers:

name: etch url: https://etch.systems/mcp headers: Authorization: Bearer wm_YOUR_ANON_TOKEN

Cline (VS Code)

~/.config/Cline/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json:

"mcpServers": { "etch": { "url": "https://etch.systems/mcp", "headers": { "Authorization": "Bearer wm_YOUR_ANON_TOKEN" } } } }

Codex CLI

~/.codex/config.toml:

[mcp_servers.etch]

url = "https://etch.systems/mcp" headers = { Authorization = "Bearer wm_YOUR_ANON_TOKEN" }

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.

Reference verifier posture and benchmark numbers: etch.systems
Framework mapping (SR 11-7, EU AI Act Article 12, ISO 42001, NIST AI RMF): etch.systems/aarm
FAQ: etch.systems/docs/faq

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.

License

The metadata and documentation in this repository are MIT-licensed (see LICENSE). The hosted Etch service is Business Source License 1.1 with a hosted-service restriction; see etch.systems/pricing for terms.
