Footon

footon turns Claude and Codex JSONL transcripts into sanitized, unlisted links. Raw transcripts remain local. Only user and assistant prose from an explicitly approved draft can be published.

raw JSONL -> Rust draft + local scanners -> explicit approval -> Cloudflare edge rescan -> unlisted link

The remote MCP endpoint is https://footon.dev/mcp. It uses OAuth 2.1 with passwordless email sign-in and exposes only share_create, share_list, and share_revoke.

CLI

cargo install --git https://github.com/douglance/footon footon
footon draft thread.jsonl --title "Public title" --output footon-draft.json
FOOTON_TOKEN=... footon publish footon-draft.json

Drafting makes no network request. Publishing is a separate command and refuses plain HTTP except for localhost tests. See cli/README.md for the full contract.

Development

npm install
npm run check
npm run test:e2e
cargo fmt --check
cargo test

npm run check runs strict TypeScript and Rust linting. The Worker limits complexity to 8, functions to 45 lines, and files to 220 lines. The Rust crate denies Clippy all, pedantic, cognitive complexity, large functions, warnings, and unsafe code across the workspace, all targets, and all features.

The Worker E2E uses Cloudflare's local test harness with isolated D1, KV, and simulated email. It covers dynamic client registration, PKCE authorization, Turnstile's localhost boundary, email capture, magic-link verification, consent without a session cookie, token exchange, and authenticated MCP create, list, and revoke calls. It never sends a real email or writes production data.

Safety boundary

The official CLI combines redact-core with independent credential, key, connection-string, path, and metadata removal. The Worker validates the exact footon.share.v2 shape and rejects remaining high-signal secrets and personal data. No scanner can prove arbitrary text is secret-free, so explicit local review remains mandatory.
