# Trader MCP Surface Proposal

Keep the public MCP surface small and standardized.

## Current tools

### 1. `list_strategies()`
Returns a compact inventory of strategies.

### 2. `get_strategy(id)`
Returns compact identity/control data plus `report` by default.
Optional flags:
- `include_config`
- `include_state`
- `include_render`
- `include_debug`
- `include_report` (defaults to true)

### 3. `update_strategy(id, config?, state?)`
Writes config/state changes for an existing strategy, then reconciles it.

### 4. `control_strategy(id, action)`
Single control entry point for `start`, `pause`, `resume`, `stop`, and `reconcile`.

### 5. `set_strategy_policy(id, policy)`
Stores Hermes policy metadata on the strategy.

### 6. `get_capabilities()`
Describes the current surface and the strategy record shape.

## Design notes

- `report().fit` is the Hermes-facing fit block.
- `set_strategy_policy()` stores high-level intent, not trading mechanics.
- policy is reapplied on reconcile and instance creation.
- `get_strategy()` should stay compact unless expanded explicitly.
- keep the surface small and predictable.
