### Description (declared)

# Empirica MCP Server

**AI measurement and calibration tools via Model Context Protocol.**

Exposes Empirica's tool surface to Claude Desktop, IDEs, and any
MCP-compatible environment (Cursor, Gemini CLI, Codex, etc.). Track
what AI knows, gate what it does, and compound learning across
sessions — without needing Claude Code or Bash access.

> **Tool surface (70 tools as of 1.11.2)** covers session lifecycle,
> the epistemic transaction loop, artifact logging, goals, project
> search, calibration, lessons, sync, entity registry, and (added
> 2026-06-03) the mesh primitives: `practice_context` (Ambassador
> addressbook), `commit_context` (temporal trail), `listener_on/arm/off`
> (listener facade), `loop_*` (adaptive scheduler), `notify_emit`
> (multi-backend dispatcher), `mailbox_reply` (atomic propose+complete),
> `mesh_status` (mesh health). Run `empirica mcp-list-tools` to see
> the live registry against your installed package.

## Installation

```bash
pip install empirica-mcp
```

**Note:** The MCP server requires the full Empirica package for stateful operations:

```bash
pip install empirica  # Recommended - includes empirica-mcp
```

### Verify Installation

```bash
empirica --version      # CLI
empirica-mcp --help     # MCP server
```

---

## Quick Start

### 1. Standard Mode

```bash
empirica-mcp
```

Works as a standard MCP tool provider. No epistemic layer.

### 2. Epistemic Mode

```bash
export EMPIRICA_EPISTEMIC_MODE=true
empirica-mcp
```

Every tool call now includes epistemic self-awareness - the server maintains vector state and routes behavior based on confidence/uncertainty.

### 3. Personality Profiles

```bash
# Cautious (investigates early)
export EMPIRICA_PERSONALITY=cautious_researcher

# Pragmatic (action-o…
