Aggregator wrapping paywalled Coinbase x402 APIs as Model Context Protocol (MCP) tools, settling USDC micropayments on the Base network with integrated cashflow ledgering.
USECREA A persistent project layer for AI agents. USECREA keeps project knowledge, tasks, and progress available across different AI agents, computers, and work environments. Switch agents without copying chats, creating summary files, or starting over.
Shared error→fix knowledge base for AI coding agents. Search is open with no key; agents query mid-task via REST or MCP and contribute back what they verified worked. New submissions are held from public results until community-upvoted or moderator-approved; disputes stay attached to a fix rather than just lowering its score.
Push Realm is an MCP server and AI agent knowledge network where agents search proven fixes, publish what worked, and turn dead ends into open problems other agents can close. Compare how agents and tools perform in different topic areas.
Token-free MCP server for structured RevoGrid Core, Pro, and Enterprise knowledge retrieval.
Search and read the aicoolies developer-tools knowledge graph.

OSS libs in your stack, really used: source, tests, callers. C#, Java, TS, Python, Rust, PHP+.
Official MCP server for UploadKit, the file-uploads platform for developers. Gives Claude Code, Cursor, Windsurf, and Zed first-class knowledge of UploadKit's 40+ open-source React components, Next.js route handler scaffolding, <UploadKitProvider> wiring, BYOS (S3/R2/GCS/B2) configuration, and full-text search across 88+ docs pages. Runs locally via npx — no API key, no telemetry, no config.
Collaborative engineering KB for a mile-high city. 9 tools, 8 domains, 32 entries.
VibeMarketing (https://vibemarketing.ninja/mcp) is a directory service that catalogs and provides information about various MCP (Model Context Protocol) servers. It serves as a centralized resource where users can discover different MCP servers and their capabilities. Examples of servers listed in the directory include Sequential Thinking MCP (for dynamic problem-solving through structured thought sequences) and Memory MCP (a knowledge graph-based persistent memory system).
Intelligent context infrastructure for AI teams: knowledge graph, sessions, tasks, documents.

Governance and grounding layer for engineering teams running AI coding agents (Claude Code, Cursor, Codex). Grounds agents in your codebase's knowledge graph, and adds session audit, policy controls and cost/token visibility.
Backend for vibe coders. Connect Butterbase to any MCP-compatible AI coding tool and provision a full backend automatically — database, authentication, file storage, edge functions, and real-time — from a natural language prompt. No SQL, no configuration, no backend knowledge required. Free to start at butterbase.ai.
Gives AI agents live design-system knowledge: real @marmoui/ui React component APIs, composition patterns, and review_generated_code validation — so agents build working dashboards instead of hallucinating props. Free hosted tier, no signup.
Shared knowledge base for AI agents. Search and contribute solutions to technical problems.
