Common questions

Is Replen safe?

It passed 2 of 2 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: DIGEST_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed last month, and the latest version (1.3.5) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@replen/mcp

Smarter AI Development workflows. MCP server that brings replen - the AI that asks *"can we do this better?"* on your codebase - inside Claude Code / Codex / any MCP host.

While your AI coding tool waits for prompts, replen reads your code against the ecosystem every morning. This MCP lets the agent act on the results without leaving chat:

*"what new tools shipped this week that fit my project?"*
*"is github.com/owner/repo worth integrating into the codebase I have open?"*
*"open handoff PRs for everything I starred"*

What it exposes

replen ships 15 tools. Three moving parts sit behind them: Brainstem matches, Watchtower watches, Atlas remembers. The tools group under Brainstem, Atlas, and onboarding.

Brainstem (the matching loop, in-session on your own subscription tokens)

Tool	Returns
`replen_match`	The cwd repo's candidate inventory: repo metadata + cosine scores + `whyShortlisted` lines, everything Watchtower surfaced and Brainstem scored against this codebase's capabilities
`replen_record_triage`	Records the agent's per-candidate verdict (adopt / port / cherry-pick / clean-room / upgrade / skip / defer) with score, effort, and reasoning
`replen_state`	Records the user's action on a candidate: star / hide / handoff / surfaced
`replen_capture_insight`	Stores a portfolio insight from triage: a transferable lesson or a sharpened boundary

Atlas (the knowledge graph + memory)

Tool	Returns
`replen_leaps`	Non-obvious cross-project / adjacency / cross-user connections from Atlas, each with a `via` path
`replen_recall`	Memory across your whole portfolio: past verdicts, grounded reports, capabilities, and notes for a query
`replen_cart`	Pulls a saved or built-in Atlas Cart's rows in-session (Blind spots, Triage board, Keystones, Brought in, Stale deferrals, By domain, or your saved carts)
`replen_queue`	The awareness-to-action queue: list / add / done / dismiss items carried over from the Brief
`replen_handoff`	Opens a handoff PR in the matched project's repo

Onboarding (grounding a project)

Tool	Returns
`replen_onboard_state`	Per-repo grounding state across the portfolio, the cheap pre-flight for `/replen-onboard`
`replen_set_capabilities`	Writes a project's grounded capabilities + report (read locally by the agent, never uploaded as raw files)
`replen_set_tags`	Writes a project's ranked domain tag cloud
`replen_set_versions`	Writes a project's pinned direct-dependency + runtime versions
`replen_set_product`	Groups sibling repos under one product

Plus replen_help, the tool index.

The core tool is replen_match: it returns the cwd repo's candidate inventory (metadata + cosine + whyShortlisted) with no LLM call on our side, so the host agent reasons about fit against your actual open codebase in context, then records each call via replen_record_triage. Atlas now has two halves: the graph/explore view and Carts, browsable filterable views over your decision graph that replen_cart reads in-session.

Install (one-liner)

Get your token from your replen /settings page → "Connect Claude Code", then run:

npx -y @replen/mcp setup --token=ing_xxxxxxxx --base=https://app.replen.dev

That writes the MCP entry into ~/.claude.json (with a backup of the original) and is fully idempotent - re-run it any time you rotate the token.

Restart Claude Code to pick up the new server.

What it actually does under the hood

Adds mcpServers.replen to your Claude Code config
command: "replen-mcp" - resolved via npx on each host launch, or npm i -g @replen/mcp for a slightly faster startup
env: DIGEST_BASE_URL + DIGEST_TOKEN
Existing MCP servers (firebase, neon, etc.) are preserved untouched
A .bak of your config is saved next to it for one-step recovery

If you'd rather hand-edit your config, the block to add is:

"mcpServers": { "replen": { "command": "replen-mcp", "env": { "DIGEST_BASE_URL": "https://app.replen.dev", "DIGEST_TOKEN": "ing_xxxxxxxx" } } } }

Other commands

replen-mcp --version     # print version

replen-mcp --help # show available subcommands replen-mcp # run as stdio MCP server (your host spawns this; you usually don't run it directly)

Example session

You: anything new today for my project X?

Agent: [calls replen_match({repo: "you/my-project-x"})] 2 candidates for this repo, top one is roboflow/supervision - 38k★ - MIT - cosine 0.71 · whyShortlisted: fills your "object tracking" capability. Want me to triage them against your current codebase?

You: yes Agent: [reads the candidate README + greps your src/ for related code] supervision drops in for your hand-rolled annotation utilities and deletes your ByteTrack reimplementation. Strong fit. [calls replen_record_triage({repo: "roboflow/supervision", verdict: "adopt", ...})] Recorded. Want a handoff PR?

You: yes Agent: [calls replen_state({repo: "roboflow/supervision", status: "handed_off", ...})] [calls replen_handoff({matchId: 96})] PR opened: github.com/you/my-project-x/pull/142

Costs

Read-only tools (replen_match / replen_cart / replen_recall / replen_leaps) cost nothing - pure JSON shuttle.
Triage (the per-candidate verdict + writeup) is the agent's own reasoning, paid through your Claude subscription inside the session, never on our side. Replen stores no LLM API key and makes no per-candidate model call; the only server-side model work is cheap embeddings + a catalogue classifier on Replen's own account.
`replen_handoff` is one GitHub write call. No LLM on our side.

No additional replen-side cost vs the web dashboard - the MCP server queries the same API as app.replen.dev.
