Ecosystem Listing: webmcp-id (agent identity) + agentpay-mcp (agent payments)

[up2itnow0822]

Following up on the earlier conversation (PR #4937, Issue #4760) where the team recommended we release as a standalone package for the ecosystem page.

We have shipped two standalone packages:

webmcp-id v1.0.0 (just published)

W3C DID-based agent identity. No blockchain required.

• did:web: identifiers resolved via DNS
• W3C Verifiable Credentials 2.0 (AgentAuthorization + AgentCapability)
• /.well-known/agent.json discovery (NAIS 1.1)
• Google A2A AgentCard adapter - identity.toA2AAgentCard()
• Ed25519 signing, JWT-VC format
• 19 passing tests, zero blockchain dependencies

npm: webmcp-id
GitHub: up2itnow0822/webmcp-id

agentpay-mcp v4.1.1 (existing)

MCP server for x402 agent payments. Multi-rail: x402 + Stripe MPP.

• 23 MCP tools (wallet, payments, identity, bridging)
• SpendingPolicy with fail-closed default
• Human-in-the-loop approval mode
• Immutable audit trail

npm: agentpay-mcp

ADK Integration

Both work with ADK agents via MCP tool integration. webmcp-id specifically includes an A2A AgentCard adapter so ADK agents can present verifiable identities in multi-agent workflows.

Production credential: NVIDIA NeMo-Agent-Toolkit-Examples PR #17 merged - first payment tool in official NVIDIA catalog.

Would love to be listed on the ADK ecosystem page as recommended for agent identity and payments.

@up2itnow0822 Thank you for bringing this. The request is under review, and I’ll keep you updated if any additional information is required. We appreciate your patience.

@klateefa Thanks for the update — appreciate the review. Happy to provide any additional details if needed. We recently shipped native Rust acceleration (wallet signing, TurboQuant memory compression) alongside the existing TypeScript SDK, so there may be interesting performance characteristics worth discussing for ADK's Python ecosystem as well.

Thanks @klateefa for the update — appreciate the review.

Quick update: we recently shipped native Rust acceleration for wallet signing and TurboQuant memory compression for agents. Would be happy to do a short demo call if helpful for the evaluation.

Let me know if any additional technical details would help move this forward.
