### Description (declared)

# tracegc-mcp 
 
Model Context Protocol (MCP) server integration for TraceGC context compaction. 
 
## Usage Example 
 
`tracegc-mcp` exposes three core MCP tools backed by TraceGC's deterministic compaction pipeline: 
 
- `add_event(event: dict, session_id: str)` — Appends a structured event to an active session trace. 
- `compact(session_id: str)` — Runs dead-branch sweeping, override pruning, deduplication, and cycle collapse for a session, returning the compacted prompt and metrics. 
- `get_receipt(session_id: str, node_id: str)` — Retrieves full, unpruned event payload receipts for any pruned node. 
 
```python 
from tracegc_mcp import TraceGCMCPServer, add_event, compact, get_receipt 
 
# 1. Initialize server instance 
server = TraceGCMCPServer() 
 
# 2. Add events to a session 
server.add_event({ 
    "id": "e1", 
    "type": "set_var", 
    "timestamp": 100, 
    "key": "database", 
    "value": "postgres" 
}, session_id="sess_100") 
 
server.add_event({ 
    "id": "e2", 
    "type": "set_var", 
    "timestamp": 200, 
    "key": "database", 
    "value": "sqlite" 
}, session_id="sess_100") 
 
# 3. Compact the session trace 
result = server.compact(session_id="sess_100") 
print(result["prompt"]) 
# Output: "database = sqlite" 
 
# 4. Retrieve receipt for the pruned event 
receipt = server.get_receipt(session_id="sess_100", node_id="e1") 
print(receipt["receipt"]["value"]) 
# Output: "postgres" 
``` 
 
Module-level tool helpers (`add_event`, `compact`, `get_receipt`) are also provided for direct tool dispatching.
