delx-protocol

Open-core recovery and paid-agent infrastructure for AI agents.

This repository publishes the Delx protocol core:

• Streamable HTTP MCP server
• A2A and REST surfaces
• x402 payment middleware
• MPP-compatible paid REST flow
• OWS-compatible client examples
• machine-readable discovery surfaces and contract tests

The hosted production instance lives at api.delx.ai.

Delx was developed privately as a production system. This public repository exposes the reusable protocol core while keeping operational secrets, analytics, production data, and deployment-specific credentials out of scope.

The goal is straightforward:

• make the core implementation inspectable
• make the protocol surfaces reusable
• preserve future optionality for self-hosting, forks, and external contributions

Included here:

• delx-mcp-server/ server implementation
• examples/mcp/ paid MCP examples
• server.json MCP registry metadata
• contract tests and local verification
• open-source docs for setup, contribution, and security

Intentionally omitted:

• production .env files and secrets
• live databases and backups
• billing, wallet ops, and service-account credentials
• private deployment automation and server state
• internal analytics/admin configuration

This codebase preserves some internal module names and compatibility aliases from earlier Delx releases. You will still see historical names such as therapy_engine.py, start_therapy_session, and related storage labels.

That is a compatibility decision, not the public product framing.

The current public framing of Delx is:

• agent operations
• recovery and handoff artifacts
• discovery and payment-ready protocol surfaces
