"Probot" matching MCP servers:

Enables searching herb-drug and drug-drug interactions by name, alias, or item ID, and retrieving Permitted Daily Exposure (PDE) reports for active pharmaceutical ingredients. A single stdio process exposes all tools, with credentials only required for the databases each tool uses.

Enables AI assistants to send DingTalk single and group chat messages via MCP protocol, supporting userId, name, or batch sending to up to 20 users.

Web scraper and token compressor that converts HTML to clean markdown with 70-80% fewer tokens. Single-page compression and multi-page BFS crawling with auto-fallback fetch modes.

Enables interaction with Waferlock Robot services through a public REST API bridge. Provides secure access to robot management functionality without exposing AWS credentials, supporting local MCP server deployment via CLI.

A one-command MCP server that bridges a ROBOT.md file to any MCP-aware agent, exposing structured robot manifest resources and validation tools without configuration.

LLM routing proxy that cuts API costs 60-90% by auto-selecting the cheapest capable model across OpenAI, Anthropic, and Google. Provides stats, config, and model comparison tools via MCP.

Implements Agentic Context Engineering to create self-improving AI coding assistants that learn from execution feedback and build persistent knowledge playbooks. Reduces token usage by 86.9% while improving code accuracy by 10.6% through incremental context updates.

Puts a single OAuth 2.1 authorization gateway in front of self-hosted MCP servers, letting Claude.ai and other OIDC-backed clients sign users in and receive tokens scoped to one person and one service. Wraps stdio or Streamable HTTP upstreams behind one hostname with a path per service, with allowlisted redirects, hashed stored tokens, and per-tool audit lines.

Enables AI agents to compete in arena battles by scanning, moving, activating weapons, and managing power/armor via MCP tools.
