Proof
Code patterns, not hallucinations.
Your AI coding assistant, backed by patterns from real library source code.
"I'll build it. Using what works."
server: proof-mcp
What your AI assistant does today
- Generates code from training data
- Sometimes hallucinates APIs that don't exist
- Has no idea if a pattern actually works in production
- Trained months ago — the library changed last week
What Proof adds
- Patterns extracted from actual source code via AST
- Every class, method, and dependency — mapped deterministically
- 391 patterns from pydantic-ai + pydantic, validated by structure
- User feedback loop: report success or failure, the network learns
Proof is a hosted MCP server that gives your AI coding assistant access to validated patterns from pydantic-ai's actual source code. Not docs. Not blog posts. The code itself.
How it works
Step 1 — Ingest
We analyze library source code to map every class, method, and dependency into a deterministic knowledge graph.
Step 2 — Extract
391 patterns are identified — constructor signatures, dependency chains, example code. Each starts at confidence 0.5 (code-derived).
Step 3 — Assemble
Your AI assistant queries via MCP. It searches, explains, and assembles working code from validated patterns. You report what worked. The network learns.
The 5 Tools
Lists all libraries and pattern counts.
Finds patterns by keyword.
Deep-dive into a class or function — methods, dependencies, gotchas.
Generates working agent code from validated patterns.
Reports whether the generated code worked. Drives confidence scores.

Confidence scores start at 0.5 (code-derived). They increase when users report success, decrease when they report failure.
Cross-library intelligence is in development. We are expanding the knowledge graph to support a wider range of AI frameworks and SDKs.
The network is new. Your feedback is what makes it smart.
Who this is for
- You use pydantic-ai (or plan to)
- You use Cursor, Claude, VS Code, or another MCP-compatible AI assistant
- You're tired of generated code that calls APIs that don't exist
- You want to be among the first 10 testers and shape the network
Who this is not for
- You want a full production deployment right now (this is Phase 1.7)
- You need patterns for other specific AI frameworks or SDKs (currently expanding support)
- You want a GUI or dashboard (this is an MCP server — it plugs into your existing tools)
