Catalog
Every x402, MPP, MCP, and skill listing we've indexed, normalized, and enriched.
OpenAPI Spec Reference Indexer
Indexes and cross-references OpenAPI 3.x specifications using swagger-parser and Redocly CLI. Builds searchable endpoint catalogs with schema resolution, authentication flow mapping, and SDK generation metadata.
OpenAPI Spec Reference Generator
Converts OpenAPI 3.x specification files into browsable API reference documentation using swagger-parser and redoc-cli. Generates static HTML, markdown, and Postman collection exports from YAML/JSON spec files.
OpenAPI Spec Navigator
Parses and navigates OpenAPI 3.1 specifications using swagger-parser and @apidevtools/json-schema-ref-parser. Resolves $ref chains, extracts endpoint signatures, and generates typed client stubs.
OpenAPI Spec Linter & Docs Generator
Validates OpenAPI 3.x specifications using Spectral rulesets and generates interactive API documentation with Redoc and Swagger UI. Detects breaking changes using oasdiff for versioned APIs.
OpenAPI Spec Compliance Checker
Validates REST APIs against their OpenAPI 3.x specifications using swagger-parser and Spectral linter rules. Checks response schemas, parameter types, authentication requirements, and generates compliance reports.
OpenAPI Spec Changelog Generator
Compares OpenAPI 3.x specification files using the oasdiff library to detect breaking changes, deprecated endpoints, and schema modifications. Outputs structured changelogs in Markdown or JSON.
OpenAPI SDK Generator Pipeline
Generates typed client SDKs from OpenAPI 3.x specifications using openapi-generator-cli. Produces TypeScript, Python, and Go clients with proper authentication interceptors and retry logic.
OpenAPI Generator API Client and Server Stub Tooling
OpenAPI Generator turns OpenAPI specs into client SDKs, server stubs, docs, and config. It is a practical fit when you need repeatable API scaffolding from a contract-first workflow.
OpenAI Whisper Transcription
Local speech-to-text transcription without relying on an API.
OpenAI Whisper API Transcription
API-based speech-to-text transcription through OpenAI. No local model downloads, no GPU, no Python ML stack — just an API key and a shell script.
OpenAI MCP Server
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
OpenAI Image Gen
Batch-generate images through the OpenAI Images API with a prompt sampler and gallery output.
OpenAI Agents SDK Multi-Agent Workflow Framework for Python
The OpenAI Agents SDK is a lightweight Python framework for building multi-agent workflows. It supports 100+ LLMs, provides built-in guardrails, handoffs between agents, MCP tool integration, tracing, sessions, and real-time voice capabilities.
OpenAI Agents SDK JavaScript Workflow Toolkit
A source-backed guide to the OpenAI Agents SDK for JavaScript and TypeScript. It covers agent orchestration, tools, handoffs, tracing, and the practical install path.
Open WebUI Self-Hosted AI Interface for LLMs
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform designed to operate entirely offline. It supports various LLM runners like Ollama and OpenAI-compatible APIs with built-in RAG inference, providing a powerful web-based interface for interacting
Open Policy Agent (OPA)
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
Open Interpreter Natural Language Computer Interface
Open Interpreter lets LLMs run code locally (Python, JavaScript, Shell, and more) through a ChatGPT-like terminal interface. It provides a natural-language interface to your computer's general-purpose capabilities including file manipulation, browser control, and data analysis.
OPA Rego Policy Bundle Tester
Tests authorization and policy bundles with the Open Policy Agent `/v1/data` and `/v1/compile` APIs plus `opa test` semantics. Great for agents that need to explain which Rego rules allow or deny a request before policy changes go live.
onefetch Git Repository Information and Statistics CLI
onefetch is a Rust CLI tool that displays project information and code statistics for Git repositories directly in the terminal. It detects languages, shows contributor stats, license info, and repo metadata with an ASCII art logo for the dominant language.
Ollama Local LLM Runner and Model Server
Ollama runs large language models locally with a simple CLI and REST API. It supports hundreds of open models including Llama, Gemma, Qwen, and DeepSeek, with GPU acceleration and an OpenAI-compatible API endpoint.
Official Firecrawl MCP Server
Official Firecrawl MCP Server exposes Firecrawl’s scraping, crawling, search, and deep research features to MCP clients. It is a strong choice for agents that need web extraction with a maintained API-backed service instead of hand-built scrapers.
Octokit JavaScript GitHub SDK for REST GraphQL and App Automation
Octokit is GitHub’s JavaScript SDK family for REST API requests, GraphQL queries, authentication, webhooks, and GitHub App workflows. It gives agents and automation systems a typed, maintained client for working with GitHub from Node.js, browsers, and Deno.
OCRmyPDF Searchable PDF OCR Pipeline
OCRmyPDF is an open source tool that adds a searchable OCR text layer to scanned PDFs. It is useful when an agent needs to turn image-based documents into text-searchable files without rebuilding a full document pipeline.
