Packages

LMQL (Language Model Query Language) is a Python superset and runtime that lets you embed LLM calls directly inside code, using templated variables plus decoding algorithms and constraints (e.g., logit masking, datatype/format constraints, stopping conditions). It supports sync/async execution, multi-model backends (e.g., OpenAI, Azure OpenAI, HuggingFace Transformers), and includes tooling such as a playground and an inference API for serving models.

Provides a bridge between MCP clients (via stdio/http) and in-process .NET apps by exposing .NET methods as MCP tools/prompts/resources. The .NET app hosts an in-app SignalR client that connects to a standalone MCP bridge server (McpPlugin.Server), which then serves MCP over stdio/http transports. Tools/prompt/resource schemas are generated from C# types using ReflectorNet, with attribute-based registration and optional fuzzy method matching.

Provides a Model Context Protocol (MCP) server that wraps ProjectDiscovery's subfinder to enumerate subdomains for a given domain via a JSON-RPC interface, including options for recursion, depth, timeouts, and source filtering/exclusion. Includes a /health endpoint for liveness.

Namecheap's XML/REST API for domain registration, DNS management, WHOIS lookup, SSL certificate management, and domain portfolio management.

SAP's OData and REST APIs for accessing enterprise business data including finance, procurement, supply chain, HR, and customer management across SAP S/4HANA and SAP BTP.

Slack integration for OpenClaw/Clawd agents

Provides a Unity Editor HTTP bridge (localhost:7890) that exposes a large set of MCP tools (268 across 30+ categories) via a companion MCP server, enabling AI assistants to inspect and modify Unity projects (scenes, GameObjects, components, assets, scripts, builds, editor/play mode actions, profiling/debugging, shaders, terrain, navigation, etc.).

webclaw is a self-hosted, local-first web scraping/extraction tool written in Rust. It fetches and extracts main content from URLs into LLM-friendly outputs (e.g., markdown/text/JSON), supports crawling and sitemap mapping, and includes an MCP server plus optional cloud API for protected/JS-heavy sites and “LLM features” (summarize/extract/search/research).

Provides an MCP server that lets AI agents interact with Windows hosts via WinRM, including interactive credential setup and remote PowerShell execution plus basic system/service/disk information tools.

Provides an MCP (Model Context Protocol) server exposing Turkish Higher Education Atlas (YÖK Atlas / YOKATLAS) data via FastMCP tools, including fuzzy program search and detailed atlas statistics for associate and bachelor degree programs.

Zillow's property data API (Bridge Interactive) providing listing data, Zestimate home value estimates, rental estimates (Rent Zestimate), and market statistics. Access is restricted to approved partners.

Low-cost S3-compatible object storage with industry-leading pricing, commonly used for backups, media storage, and cost-sensitive workloads.

Lightweight MCP server that enables AI assistants to execute AppleScript commands on macOS, providing control over native Mac applications like Notes, Calendar, Contacts, Messages, and Finder.

An open-source AI chatbot platform that unifies multiple LLM providers (OpenAI, Anthropic, Google, xAI, Ollama) in a single Next.js interface with MCP tool support, custom agents, visual workflow builder, and real-time voice.

Context Mode is an MCP-focused “context virtualization” layer for AI coding agents. It provides sandbox tools to keep large raw tool outputs out of the model context, tracks editing/tool/task/error/user events in a local SQLite database, and uses FTS5/BM25-style search to retrieve only relevant past events during context compaction so the agent can resume continuity.

Decodo is an MCP server that integrates web scraping and data extraction capabilities with LLMs and AI applications. It provides access to web scraping tools including general website scraping, Google Search scraping, Amazon product search, and Reddit content extraction with features like geographic IP rotation, JavaScript rendering, and content truncation.

deepcontext-mcp is an MCP server that indexes a local codebase using AST-based parsing (tree-sitter) and builds a hybrid semantic search index (vector similarity + BM25 reranked with Jina). It exposes MCP tools to index code, search code, check indexing status, and clear indexes, enabling coding agents to retrieve more relevant code context than keyword search.

knowledgebase-mcp (BioContextAI) is an MCP server for biomedical research that exposes standardized MCP “tools” to let agentic LLMs query multiple biomedical knowledge sources (e.g., EuropePMC, Ensembl, InterPro, Reactome, STRING) through a unified integration layer.
