Finds real, maintained open-source repos that fit your project. MCP grounding for coding agents.
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.
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.
Read-only AI project discovery, verification, comparison, shortlisting, and stack planning.
Evidence-backed open-source project search, recommendations, alternatives, and comparisons.
Icons for agentic development: search & fetch 366,000+ open-source icons as SVG/PNG. No API key.
Discover open-source AI agents and get source-owned installation instructions through MCP.
Grade MCP servers A to F with the open behavioral litmus. npm: full toolset; hosted: lookups only.
Trust signals for AI agents: an open agent-readiness standard and developer tool guide. Read-only.
Unpaid qualification-gated operational_context canary. Staging data. No wallet.
Measured readings on open-source dependencies: health, end-of-life, model prices, incidents.
320K+ open-source SVG icons: 12 tools, anonymous metadata search; SVG, exports, collections via Pro.
Measured readings on open-source dependencies: health, end-of-life, model prices, incidents.
Search independent software the big engines bury: indie apps, open-source repos, and dev tools.
Search and fetch icons from 200,000+ icons across 100+ open-source libraries. Supports Material Design, Lucide, Heroicons, Phosphor, Tabler, Font Awesome, and more. No API key required.
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.
Self-hosted, open-source MCP gateway: turn any API, database or MCP server into custom connectors for Claude, ChatGPT, Gemini, Copilot & Cursor — no code. Converts REST, SOAP, WSDL, GraphQL & SQL to MCP, with OAuth2, RBAC & audit log. 175+ pre-built adapters. This is the public read-only demo endpoint — run your own at https://github.com/HelpCode-ai/anythingmcp
It connects with Smart Data models database with more than 1000 open licensed data models and helps you to create applications and systems interoperable with existing standards or real applications
The OpenZeppelin Stylus Contracts MCP server generates secure smart contracts for the Arbitrum Stylus environment using OpenZeppelin templates, including ERC-20, ERC-721, and ERC-1155 standards. It automatically validates generated code against OpenZeppelin's security and style rules, enforcing best practices for imports, modifiers, naming conventions, and security checks to prevent common vulnerabilities. The server integrates with AI development tools like Cursor, Claude, Gemini, Windsurf, and VS Code to enable AI-assisted, production-ready smart contract development.
