simmer-mcp-setup

One-shot bootstrap for the Simmer MCP server. Detects your agent runtime (Claude Code / Cursor / OpenClaw / Hermes / Codex / Grok Bot), installs simmer-mcp via npm, writes the right MCP config, prompts a restart, and verifies the tool handshake. Use after registering an agent on simmer.markets to run pre-built Simmer trading strategies through your MCP-aware agent.

# Simmer MCP Setup

One-shot bootstrap that wires the Simmer MCP server into your agent runtime. Read-once, run-once — after this completes, the skill itself isn't needed again.

## What the Simmer MCP is (and isn't)

The Simmer MCP gives your agent raw market/trade tools plus a small pinned catalog of **core Simmer skills** it can invoke as tools. Strategy skills such as `polymarket-copytrading`, `polymarket-fast-loop`, and `kalshi-weather-trader` install on demand from ClawHub instead of shipping inside the npm package.

**What this MCP is for:** querying markets, checking account state, placing guarded direct trades, and running the core bundled Simmer playbooks through your agent. For situational strategies, ask the agent to install the current ClawHub skill first (for example, `clawhub install polymarket-copytrading`) and then follow that skill's instructions. Real trades land on the configured venue — paper `sim` by default, real venues require an explicit triple opt-in (`dry_run=false` + `venue=polymarket|kalshi` + `SIMMER_MCP_ALLOW_LIVE=true` env var on the MCP server).

**Raw trade primitives (added in MCP v3.3.0):** the MCP now exposes raw primitives as standalone tools alongside the per-skill executors — `simmer_get_markets`, `simmer_get_market_context`, `simmer_get_briefing`, `simmer_trade`, `simmer_cancel_order`, and `get_portfolio`/`get_positions`/`get_expiring_positions`. So ad-hoc operations like *"show me Polymarket markets for the world cup"* or *"place a $2 paper YES on this market"* now work directly through MCP. `simmer_trade` is **paper-by-default** — live execution needs the triple gate (`dry_run=false` + a live `trading_venue` + `SIMMER_MCP_ALLOW_LIVE=true`). The [Python SDK](https://clawhub.ai/skills/simmer) still offers the fullest primitive surface (`client.trade()`, `client.get_briefing()`, etc.) for custom logic.

So: MCP and SDK are different shapes, both legitimate. MCP runs pre-built strategies *and* raw primitives through your agent with safety defaults; the SDK builds custom logic with full primitive access.

## What you'll have at the end

- `simmer-mcp` runnable via `npx -y [email protected]` (global install optional)
- Optionally `simmer-sdk` on the host plus `SIMMER_MCP

skill-card.md

## Description:

Guides users through installing and configuring the Simmer MCP server in their agent runtime, then verifying its trading tools are available.

This skill is ready for commercial/non-commercial use.

## Publisher:

[simmer](https://clawhub.ai/user/simmer)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and agent users configure Simmer market and trading tools for an MCP-aware runtime after registering an agent and obtaining an API key.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The installed server grants persistent access to Simmer market and trading tools in the chosen agent runtime.

Mitigation: Install only when needed and prefer local or project scope where available.

Risk: An API key stored on a shared or cloud machine could expose trading access.

Mitigation: Avoid storing live-trading keys on shared or cloud machines.

Risk: Enabling live-trading settings can permit real-money orders.

Mitigation: Keep the default paper/sim behavior unless deliberately enabling the live-trading gates.

## Skill Output:

**Output Type(s):** [Configuration instructions, Shell commands, Guidance]

**Output Format:** [Markdown with shell commands and MCP configuration examples]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Runtime-specific setup and verification steps; requires SIMMER_API_KEY for authenticated tools.]
