# library_lineage_graph

Read-only, offline tool that scans the vault library (Recipes, Shaders, Presets, Components, Setlists), extracts lineage frontmatter (parent_recipe, source_assets, remix_of, forked_from), and emits a lineage graph. Output as JSON (machine-consumable), Mermaid (paste into docs), or Graphviz DOT. No TouchDesigner connection required.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "library_lineage_graph",
    "arguments": {}
  }
}
```

## Why library_lineage_graph is rated Low

This tool performs data retrieval and analysis of existing library metadata. It extracts lineage frontmatter and outputs structured data in multiple formats (JSON, Mermaid, Graphviz DOT). There are no side effects, no code execution, no data modification, and no destructive operations. The explicit 'read-only' and 'offline' qualifiers confirm it is a passive query tool.

From the tool's own definition: "'Read-only, offline tool that scans the vault library... and emits a lineage graph.' The tool retrieves and queries metadata from local library files without modifying, executing, or deleting anything."

## Use case

AI agents call library_lineage_graph to retrieve information from tdmcp — TouchDesigner MCP server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches tdmcp — TouchDesigner MCP server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "library_lineage_graph": {}
  }
}
```
