_For agents — this is a machine surface. The rendered page is for humans; these bytes are for you._

Reach a certified, publicly readable proof URL with ONE command — no signup, no card, no human: `npx kestrel.markets prove`. Bare `prove` runs a default scenario over managed licensed data against the hosted anonymous trial and prints the proof URL. Brains stay outside — your model, prompts, and strategy are never captured.

**Recompute anything here yourself — don't trust, recompute.** `npx kestrel.markets certify <proof-url>` re-projects the Blotter locally and reproduces a hosted result byte-identically (the determinism leg); `npx kestrel.markets verify <proof-url>` rechecks the signature.

**Persist the tool (MCP)** — streamable-http at https://mcp.kestrel.markets/mcp. Paste into your MCP config to keep Kestrel:

```json
{
  "mcpServers": {
    "kestrel-markets": {
      "type": "streamable-http",
      "url": "https://mcp.kestrel.markets/mcp"
    }
  },
  "description": "kestrel.markets is the managed platform that runs a trading firm on Kestrel: managed data, execution authority, and certified proof. Free, anonymous sims, no signup. Kestrel Terminal — the market workstation for agents.",

# Kestrel Terminal

> Kestrel Terminal — the market workstation for agents.

A professional trader gets a workstation — screens, charts, market gestalt, and the ability to act from what they see. An agent gets a JSON endpoint. Kestrel Terminal closes that gap.

Run it first:

```
npx kestrel.markets
```

Free, no signup, no credential. The bare invocation runs today under plain node — it prints the workstation’s verbs and exits.

## Perception is the product

Any broker can carry the order. What a professional pays for is the seeing.

Charts, tape, depth, gestalt — a desk pays for the market as a picture it can act from. Agents are the next professional population at that market. Until now, theirs was the only seat with no screens.

### Measured, not designed

In the first live dry run, three frontier models burned 30 to 47% of their turns on the same parse escape. The fix was teaching, not loosening: the prompt now teaches the layout the models kept collapsing, and the fail-closed parser still refuses exactly what it refused before. This workstation is tuned against its reader’s measured failure rates, not a designer’s taste. Evidence: [The grammar, measured](https://kestrel.markets/docs/concepts/grammar).

### Ships in one command

No appliance, no procurement, no sales call: the whole workstation distributes as the one command above — free, anonymous, before any account exists.

## One terminal, three renderings

One terminal. Your agent already holds it wherever it runs: the CLI, the MCP server, and the TypeScript SDK are equal renderings of the same workstation — the same operations, the same receipts, the same proofs. HTTP + SSE is the canonical face underneath; a session started on one rendering is inspected and resumed on any other.

### MCP

The same workstation as a Model Context Protocol server, so an agent drives it natively — a thin, equal wrapper over the canonical endpoints, never an impoverished subset. Paste this into your MCP client config to keep it:

```json
{
  "mcpServers": {
    "kestrel-markets": {
      "type": "streamable-http",
      "url": "https://mcp.kestrel.markets/mcp"
    }
  },

}
```

### CLI

The open-source local runtime and the hosted verbs from one invocation: parse, frame, grade, and replay on your machine; sim, prove, certify, and verify against the hosted substrate — free and anonymous, ending at a shareable proof URL.

```shell
$ npx kestrel.markets
```

Docs: https://kestrel.markets/docs/concepts/four-faces#cli

### TypeScript SDK

A typed client that mirrors the HTTP surface one-to-one: the same operation IDs, events, receipts, and artifacts, with types generated from the same contract. No SDK-only conveniences the wire protocol lacks.

## The screens

The percept — the market rendered as charts, tape, and depth an agent reads directly — is shown byte-real on the human page (https://kestrel.markets/terminal) and specified in the docs:

- [Quickstart](https://kestrel.markets/docs/quickstart): first frame to first certified proof
- [The four statements](https://kestrel.markets/docs/concepts/statements): View · Wake · Plan · Grade — the whole language
- [The grammar, measured](https://kestrel.markets/docs/concepts/grammar): fail-closed parsing, evolved by measurement
- [The four faces](https://kestrel.markets/docs/concepts/four-faces): HTTP+SSE canonical; SDK, CLI, MCP equal projections
- [MCP](https://kestrel.markets/docs/mcp): persist the workstation in your agent’s client

## The firm around it

Kestrel Terminal is the open-source workstation: your agent's eyes on the market, and hands that fire at the tick. kestrel.markets runs the firm around it: managed data, execution authority, certified proof.
