Recurser CLIThe command-line harness for commercial lending
Your terminal is now
a deal desk.
Recurser drives CSG-1003 applications and the Intake agent from a single command — the same Core Service the portal and the MCP server call, with the same audit trail.

Install
Build it today. Registry install is next.
The binary is recurser, with csg kept as an alias for existing scripts. The workspace package is not published yet, so the only path that works right now is building from the repo.
npm
planned@capitalsource/cli is still private at 0.0.0. Not published yet.
$npm i -g @capitalsource/cli
Homebrew
plannedNo tap exists yet. Tracked for a later release.
$brew install capitalsourceai/tap/recurser
# Then, from the repo root:
pnpm --filter @capitalsource/cli dev auth login --token csg_pat_live_…
pnpm --filter @capitalsource/cli dev doctor
Command grammar
Five verbs. Every deal in one shell.
doctor, auth, apps, agent, mcp. Pipe it, script it, cron it. Every LLM-backed call writes a usage_events row in the same transaction as the response — whether you typed it or your agent did.
Apps
shippingThe deal. A CSG-1003 from draft to certified package.
- $recurser apps create
Opens a draft CSG-1003 and prints its id. Takes no arguments.
- $recurser apps chat <id> "Acme HVAC LLC, Texas, $150k WC, 3 yrs in biz"
Streams the Intake agent's SSE events as newline-delimited JSON.
- $recurser apps qualify <id>
Runs the gating engine and flips status to qualified.
- $recurser apps certify <id> --full-name "Dana Ruiz" --ssn-last-4 4821
FCRA credit authorization + signature. Persists the certified package.
- $recurser apps package <id>
Fetches the certified package payload, including the signed PDF URL.
Agents
shippingThe CLI's own agent registry — six entries, one of them callable today. It is a narrower list than the eleven-agent catalog on /agents.
- $recurser agent list
The six agents in the CLI registry with model assignment and implementation status.
- $recurser agent show chaser
Metadata for one agent. BirdDog’s lookup key is the Prisma enum value, chaser.
- $recurser agent chat intake --app-id <id> "we bill net-60 and need $150k"
Intake is the only callable agent. Streams the same events as apps chat.
MCP
shippingThe bridge. Make Claude Desktop a CapitalSource client.
- $recurser mcp install
Writes a csg entry into Claude Desktop's config with your stored token. --client claude-desktop is the only supported host.
- $recurser mcp serve
Runs the MCP server in-process over stdio. Claude Desktop launches this for you; there is no HTTP flag.
Auth & ops
shippingCredentials and diagnostics.
- $recurser auth login --token csg_pat_live_…
Stores the PAT in ~/.csg/config.json. --token is required — there is no browser or device flow yet.
- $recurser doctor
Preflight: Node version, stored credentials, Core reachability.
On the roadmap
plannedShapes we intend to ship. None of these do the job yet.
- $recurser agent chat underwriter "credit memo for <id>"
Parses today, then raises AgentNotAvailableError. Processor and Underwriter are built, but this CLI chat binding is unavailable. BirdDog, Closer, and Recruiter also have no chat binding here.
- $recurser apps submit <id> --funder fnd_blueacme
Funder dispatch. The Funder model exists in the schema; the endpoint and command do not.
- $recurser funders list --product mca
Read the funder registry and submission templates.
- $recurser usage --by surface
GET /v1/usage/by-surface already exists in the REST API; the CLI wrapper does not.
CapitalSource Agent Harness · Processor pilot
A command line for your stack. An agent harness in Core.
Use Recurser for supported application commands and MCP setup. The CapitalSource Agent Harness powers the Processor readiness pilot in the Core worker, keeping task progress, approval decisions, and spending records together.
Where it fits your stack
- Prepare and inspect CSG-1003 applications with the CLI’s existing commands.
- Configure the Processor pilot in Flows and inspect its agent execution history.
- Use REST or the TypeScript SDK when your integration needs harness task controls.
Dedicated Recurser harness commands are not available yet. The current pilot is managed through REST, the SDK, and the portal.
MCP bridge
Make Claude Desktop a CapitalSource client.
Recurser doubles as a Model Context Protocol server. One install command wires Claude Desktop to the CSG-1003 tools, so your assistant can open, advance, qualify, and certify an application without leaving the chat.

Why Recurser
CSG-1003 is the protocol. Recurser is the command line.
Recurser gives people and their agents a command-line surface for the headless Core. CSG-1003 standardizes the application; Recurser lets you work with it from a shell. The CapitalSource Agent Harness manages the Processor pilot’s execution inside Core.
The CLI is one of four clients of the same Core Service. The others are the REST API, the MCP server, and the portal. Same auth, same router, same usage rail — pick the surface that fits the task.
