Taas

A local MCP server that exposes Tread's trading-data and order tools to a local LLM. It is a thin, generic proxy: it holds no hardcoded tools — on startup it fetches the tool catalog from your Tread backend and forwards each call there. All reasoning happens in your local agent; Tread executes the individual tool calls.

Backend dependency. This client talks to the Tread backend mcp_api endpoints (GET /api/mcp/tools, POST /api/mcp/dispatch, GET /api/mcp/guide), which must be deployed and the MCP feature flag enabled for your user. Design / PRD: Linear project "MCP Server — Local-LLM Trading Data & Orders".

What it exposes

Whatever the backend registry advertises — market data, balances, portfolio analytics, order status, and trading (single, market-maker, delta-neutral, and batch orders, plus cancel / pause / resume / set leverage). Because the catalog is fetched live, adding or changing a tool on the backend needs no new release here.

It also exposes the authoritative operating guide as the tread_operating_guide prompt, fetched live from the backend — load it before driving the tools.

Install

First install uv — this is the only prerequisite. The uvx command used below ships with uv (it's shorthand for uv tool run), so there is nothing else to install:

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
# or, with Homebrew
brew install uv

Then install and run straight from the repo — no clone required. uvx fetches the package from GitHub, builds it in an isolated environment (provisioning a compatible Python automatically), and runs the taas-mcp entry point:

uvx --from git+https://github.com/tread-labs-public/taas_mcp.git taas-mcp

The server speaks MCP over stdio, so it's normally launched by your MCP client (see Connect your MCP client) rather than run interactively. The command above is the same one you put in the client config.

Pin to a branch or tag by appending @<ref>:

uvx --from git+https://github.com/tread-labs-public/taas_mcp.git@main taas-mcp

To install it once as a persistent tool on your PATH (so the command is just taas-mcp), use uv tool instead:

uv tool install git+https://github.com/tread-labs-public/taas_mcp.git
uv tool upgrade taas-mcp   # pull a newer version later

[!NOTE] uvx caches the build. After the backend ships changes that only affect this client, force a rebuild with uvx --refresh --from git+https://github.com/tread-labs-public/taas_mcp.git taas-mcp.

Configuration

Var	Required	Description
TREAD_URL	yes	Base URL of the Tread server, e.g. https://app.tread.fi
TREAD_MCP_TOKEN	yes	Your MCP token (generate/regenerate it in the Tread web UI)
TREAD_READONLY	no	1 to hide all write/trading tools
TREAD_TIMEOUT	no	HTTP timeout in seconds (default 30)

The token can be generated from app.tread.fi by accessing the Settings > Security page

The token authenticates as you; every call is scoped to your account server-side. One running server == one Tread user. The token expires after a peiod (default 30 days) of inactivity (it is refreshed on each use); once expired, requests return 401 and you regenerate it from the Tread web UI.

Connect your MCP client

Point your MCP client at the same uvx command. The client launches the server on demand and passes configuration through env.

Claude Code (CLI)

claude mcp add tread \
  --env TREAD_URL=https://app.tread.fi \
  --env TREAD_MCP_TOKEN=your-token-here \
  -- uvx --from git+https://github.com/tread-labs-public/taas_mcp.git taas-mcp

Add --env TREAD_READONLY=1 for a read-only setup.

      }
    }
  }
}

For a read-only setup, add "TREAD_READONLY": "1" to env.

[!NOTE] The client must be able to find uvx on its PATH. If it can't (common on macOS GUI apps), use the absolute path from which uvx as command, e.g. /opt/homebrew/bin/uvx.

Develop

Clone the repo for local development, then sync and test:

git clone https://github.com/tread-labs-public/taas_mcp.git
cd taas_mcp
uv sync
uv run pytest

Run your local checkout directly (point the client at this command to test changes before pushing):

uv run --directory /path/to/taas_mcp taas-mcp

Safety

The local agent owns risk. Tread runs no server-side agent for these calls — there is no automated margin management, invariant enforcement, or liveness rescue behind them. See the tread_operating_guide prompt for the operating contract.
