Domain knowledge for Singularity Layer — workflow patterns, data models, and gotchas for your AI agent.
The Singularity Layer connects AI agents with a decentralized marketplace of API endpoints, products, and blockchain-integrated agents. This platform bridges traditional API commerce with crypto payments through the x402 protocol and supports ERC-8004/Solana-8004 agent standards.
Marketplace Discovery: Browse listings with rich filtering, search featured and top-rated endpoints, explore categories across supported blockchain networks. Access detailed information about specific products and services.
Endpoint Management: Create, configure, and monitor your own API endpoints with credit balancing, usage analytics, and pricing controls. Set up webhooks for real-time notifications and manage endpoint lifecycles.
Blockchain Agent Integration: Register and manage ERC-8004/Solana-8004 compliant agents using wallet-first authentication. Submit reputation feedback and bind platform endpoints to on-chain agent identities.
Payment Processing: Handle x402 payment challenges for endpoint creation, credit top-ups, and product purchases. Complete transactions using crypto wallets with automatic credit management.
The platform organizes around Endpoints (API services with pricing), Products (purchasable items), Agents (blockchain-registered AI services), and Networks (supported blockchains). Each endpoint maintains credit balances, usage metrics, and webhook configurations.
Authentication uses Personal Access Tokens (PATs) for dashboard operations or endpoint-specific API keys. Wallet signatures are required for blockchain agent operations. Payment flows require two-step challenges: first obtain payment details, then complete with valid X-Payment payload.
Resources provide cached access to featured listings, categories, networks, and agent registries for efficient browsing without repeated API calls.

Open in StudioThis server facilitates marketplace interactions, allowing users to browse listings, manage endpoints, and set webhooks. It is aimed at developers looking to integrate marketplace functionalities into their applications. It provides MCP tools that your client discovers when it connects (this page may not list every tool name) that AI agents can use through the Model Context Protocol (MCP).
Add the MCPBundles server URL to your MCP client configuration (Claude Desktop, Cursor, VS Code, etc.). The URL format is: https://mcp.mcpbundles.com/bundle/singularity-mcp. Authentication is handled automatically.

Singularity Layer is a remote MCP server. The live tool list is supplied by the server when your MCP client connects, so the count is not fixed on this public page. After you connect in MCPBundles Studio or your client, you will see the tools your session can call. A SKILL.md is still included to guide your agent on capabilities and workflows.
Singularity Layer uses API Key. Singularity Layer requires credentials. Connect via MCPBundles and authentication is handled automatically.
MCPBundles is an independent platform built on the open Model Context Protocol standard. Not affiliated with Anthropic PBC or Claude.
