Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "thinchain": {
      "command": "uvx",
      "args": [
        "thinchain"
      ]
    }
  }
}

Run this in your terminal

claude mcp add thinchain -- uvx thinchain

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "thinchain": {
      "command": "uvx",
      "args": [
        "thinchain"

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "thinchain": {
      "type": "stdio",
      "command": "uvx",
      "args": [

Common questions

Is Thinchain safe?

It passed 1 of 1 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 –, and the latest version (0.1.1) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

ThinChain

The catalytic converter between raw broker data and your AI trading agent.

Battle-tested. Sanitization logic extracted from a production options trading app. Handles every bad tick Tradier has thrown at us in production.

☁️ Moving to production?

The open-source server runs locally with your own API keys. For hosted infrastructure with multi-broker failover, SLA guarantees, and webhook alerts — join the managed cloud waitlist.

The Problem

Tradier's MCP dumps 500-row JSON chains. One bad print can corrupt an agent's reasoning. ThinChain sanitizes, compresses, and circuit-breaks that data before it reaches your model.

Installation

git clone https://github.com/snipmcp/thinchain.git

cd thinchain pip install -e ".[dev]" cp .env.example .env

Or with Docker:

docker-compose up --build

Configuration

TRADIER_API_KEY=your_key_here

TRADIER_BASE_URL=https://api.tradier.com/v1 POLYGON_API_KEY=your_key_here POLYGON_BASE_URL=https://api.polygon.io DEFAULT_BROKER=tradier CACHE_TTL_SECONDS=30 LOG_LEVEL=INFO

Usage

Three example prompts to send to Claude (or any MCP-compatible agent):

Use get_compressed_chain to get an iron condor setup on SPY expiring 2026-06-19
Check if SPY options data is trustworthy before I place my trade
Get me the ATM straddle strikes for AAPL expiring 2026-06-19

Run it in two terminals

# Tab 1 — start the MCP server

python -m thinchain.server

# Tab 2 — call a tool from a Python shell or your MCP client

Tool signatures:

get_compressed_chain(symbol, expiration, strategy="raw",

delta_range=None, broker="tradier")

get_sanitized_quote(symbol, broker="tradier")

get_circuit_status(symbol, expiration, broker="tradier")

How it works

Three layers between raw broker output and your model:

Broker API → [Sanitize] → [Compress] → [Circuit Break] → MCP Tool → AI Agent

hygiene strategy anomaly gate rules slicing + cache

Sanitize: Drops ghost quotes (0.0/0.0), inverted spreads, NaN/empty/dash values, clamps deltas to [-1, 1], normalizes positive theta on long options, flags illiquid strikes.
Compress: Slices the chain to only the strikes relevant to your strategy (iron condor, straddle, etc.) — typically 95%+ token reduction.
Circuit Break: Four-tier data quality (clean / noisy / degraded / circuit_breaker_active). When >65% of rows are anomalous, refuses to serve stale data and falls back to last known-good cache.

Real numbers from a live SPY iron condor (2026-06-19 expiration)

RAW TRADIER PAYLOAD          THINCHAIN OUTPUT

───────────────────────────────────────────── Rows: 482 Rows: 25 Est tokens: 38,560 Est tokens: 2,000 Token savings: 95% Anomalous rows removed: 217 Data quality: noisy → still safely served

ThinChain compresses 482 rows / 38,560 tokens down to 25 rows / 2,000 tokens — and flags 217 anomalous strikes (illiquid, ghost quotes, wide spreads) that would have polluted the agent's context.

Roadmap

Managed cloud tier (hosted, multi-tenant, webhook alerts)
Polygon connector hardening (live SIP feed)
Webhook alerts for circuit breaker trips
