WHAT IS THIS?
Lobby ships an MCP server — a small endpoint your AI coding agent (Claude Code, Cursor, Gemini CLI, opencode, Antigravity, …) can connect to in order to do useful work against Savi's internal systems on your behalf.
Today it gives your agent read-only access to our internal MongoDB databases, read-only access to Railway (services, configs, logs), and a way to check your Savi identity. More tools will land here over time.
SERVER URL
Point your agent at this URL:
…
The first time you connect, your browser will open a Savi sign-in page. Approve once and your agent stays connected.
THINGS YOU CAN ASK YOUR AGENT — MONGODB
- “Which Mongo instances does lobby know about?”
- “List the collections in the
sf1database on the dev instance.” - “Describe the shape of the
userscollection — what fields are there and what types?” - “Show me the indexes on the
transactionscollection.” - “Find the 10 most recent transactions for user
user_abc123.” - “How many sessions were created in the last 7 days?”
- “Aggregate transactions by category and give me the top 5.”
Everything is read-only. The Mongo tools cannot insert, update, or delete — they will refuse any write-shaped query.
THINGS YOU CAN ASK YOUR AGENT — RAILWAY
- “Which Railway projects does lobby have access to?”
- “List the services in the
savi-financeRailway project.” - “Show me the environments on that project.”
- “What’s the current configuration of the
lobbyservice in production — build command, replicas, healthcheck?” - “What variable names are set on the
sf1/apiservice in production?” - “Pull the last 200 deploy log lines for the latest
lobbydeployment.” - “Show me the build logs from that failed deployment.”
- “Who am I signed in as?”
Read-only and allowlisted. Lobby only talks to Railway projects explicitly allowlisted in its config — even though the underlying workspace token could reach more. Variable values are always redacted; only names are surfaced.
CONNECT — CLAUDE CODE
Run this once in your terminal:
…
Or add this to ~/.claude.json under mcpServers:
…
CONNECT — OPENCODE
Add this to ~/.config/opencode/opencode.json (or your project’s opencode.json):
…
CONNECT — CURSOR
Add this to ~/.cursor/mcp.json for all projects, or to .cursor/mcp.json at the root of a single project:
…
Then open Cursor Settings → MCP and toggle savi-lobby on.
CONNECT — GEMINI CLI
Add this to ~/.gemini/settings.json:
…
Note the key is httpUrl (Gemini CLI’s name for HTTP-transport servers), not url.
CONNECT — ANTIGRAVITY
In Antigravity, open Settings → Customizations → Open MCP Config and add:
…
Antigravity uses serverUrl (not url) for HTTP servers. Save the file and hit refresh in Installed MCP Servers.
