Phase 1 of exobrain architecture. Ships TS MCP server as a static
binary so users on machines without Node can run KeiSeiKit (USB /
flashdrive / air-gapped scenarios).
.github/workflows/release.yml (+62 LOC) — new build-mcp-binary job:
- 5-target matrix: darwin arm64/x64, linux arm64/x64, windows x64
- bun build --compile, linux arm64 continue-on-error (ARM runners
less reliable)
- Artifact kei-mcp-server-<os>-<arch>[.exe] + sha256
- release job now needs [build-release, build-mcp-binary]
install/lib-rust.sh (+50 LOC) — have_prebuilt_mcp_server() +
report_mcp_server_binary_status(); KEI_SKIP_MCP_BUILD=1 env
flag skips bun/npm install when a prebuilt binary is present.
File 165 LOC (<200 limit).
_ts_packages/packages/mcp-server/package.json — scripts.build:native
+ 5 per-target aliases (macos-arm, macos-x64, linux-x64,
linux-arm, win-x64) for local dev.
_ts_packages/packages/mcp-server/BUILD.md (NEW, 52 LOC) — local
compile guide per platform + Gatekeeper/code-sign notes +
cites bun docs [VERIFIED: https://bun.sh/docs/bundler/executables].
README.md pre-built-binaries section gains 'MCP server binary'
subsection (download, chmod +x, xattr -d com.apple.quarantine for
macOS, UAC note for Windows).
CHANGELOG.md [Unreleased] bullet added.
Output size: ~90 MB per binary (bundled bun runtime). Acceptable
trade for zero-dep USB distribution.

KeiSeiKit TypeScript Packages
v0.14.0 part B: MCP server layer + external-API adapters.
RULE 0.2 exception
TypeScript is chosen here under RULE 0.2 exception #4 (Browser/DOM adjacent) because:
- The official Model Context Protocol SDK is TypeScript-native; Rust MCP libraries are immature (as of 2026-04).
- The API adapters rely on JS-native SDKs with no Rust equivalents:
grammy(type-safe Telegram bot)googleapis(official Google API SDK for Gmail + YouTube)youtube-transcript(Tier-1 free transcript extractor)
- Async, JSON-heavy glue code is TypeScript's sweet spot.
Core primitives (signing, ledger, graph, memory, refactor, etc.) remain
Rust in ../_primitives/_rust/. This TS layer is a THIN wrapper: it
spawns the Rust CLIs as subprocesses and exposes them as MCP tools, plus
the six adapters above that have no Rust equivalent.

Install (for end users)
1. Install workspace deps
cd _ts_packages
npm install
npm run build
2. Link each package as a global CLI (optional)
npm i -g ./packages/mcp-server
npm i -g ./packages/telegram-adapter
# ... etc
Or install into a Claude agent directory:
npm i --prefix ~/.claude/agents/_ts_packages/packages/mcp-server \
./_ts_packages/packages/mcp-server
Environment variables (RULE 0.8 — secrets in ~/.claude/secrets/.env)
| Var | Package | Purpose |
|---|---|---|
TELEGRAM_BOT_TOKEN |
telegram-adapter | Bot API token |
RECALL_API_KEY |
recall-adapter | Recall.ai API key (Zoom meetings) |
XAI_API_KEY |
grok-adapter | xAI Grok API key |
GMAIL_CLIENT_ID |
gmail-adapter | Google OAuth2 client id |
GMAIL_CLIENT_SECRET |
gmail-adapter | Google OAuth2 client secret |
GMAIL_REFRESH_TOKEN |
gmail-adapter | Long-lived OAuth2 refresh token |
YOUTUBE_API_KEY |
youtube-adapter | YouTube Data API v3 key |
KEI_MCP_AUTH_TOKEN |
mcp-server | HMAC token for tool callers |
KEI_RUST_BIN_DIR |
mcp-server | Override directory holding Rust primitive CLIs |
All are read via process.env. Hardcoding tokens is forbidden (RULE 0.8).
MCP server integration
The @keisei/mcp-server exposes the Rust primitive CLIs as MCP tools. The
pattern is one Rust binary = one MCP tool, with the kei meta-tool on
top that routes natural-language queries via kei-router.
Stdio mode (for Claude Code native integration):
npx @keisei/mcp-server --stdio
HTTP mode:
npx @keisei/mcp-server --port 3000 --auth-token-file ~/.claude/mcp-token
Verification
npm install
npm run build --workspaces
npm run test --workspaces
All six packages compile under strict: true. Total new LOC: see commit.
Migration notes
- Zero impact on existing KeiSeiKit users unless they opt into the MCP
server (planned v0.14.1 installer flag
--enable-mcp). - The Rust primitives are unchanged; this layer only wraps them.
- Gmail and YouTube adapters are new (gaps in LBM).
