"Mix" matching MCP servers:

Style-aware auto-mixing and mastering for Ableton Live, providing tools for analysis, preview rendering, and release checks.

An MCP server that enables any AI agent to call Claude using your existing Max/Pro subscription via OAuth, avoiding additional API billing.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

Model Context Protocol (MCP) server for Mexican Electronic Invoicing (CFDI 4.0, Complemento de Pagos 2.0). Provide tools to validate, generate, and explore API specifications for SAT/PAC interoperability.

Enables MCP-compatible AI assistants to run Python code on Google Colab GPU/TPU runtimes, supporting accelerators like T4, A100, H100, with background execution and Google Drive integration.

Multi-agent swarm orchestrator for AI workflows. Exposes blackboard read/write, agent dispatch, permission gating (AuthGuardian), token budget enforcement (FederatedBudget), and audit log tools over MCP. Supports 14 AI framework adapters including LangChain, AutoGen, CrewAI, Codex, and A2A — mix any frameworks in one swarm with race-condition-safe shared state.(Traffic light for agents)

▎ Check an email before an AI agent sends it: send / ask a human / block — with machine reason codes and prompt-injection detection.

Enables scanning Python repos for dead code and automatically drafting a branch + PR for the safe subset (unused single-name imports) after running the repo's full test suite. All other findings are reported without modification, and a human always merges.

Enables communication between Claude Code sessions in iTerm2 panes, primarily for notifying other sessions when a PR is merged to main so they can pull latest changes.

Live and historical electricity prices, demand, generation mix and carbon intensity for 25 grid zones (US, Europe, GB, Australia). Hosted endpoint plus local stdio bridge; free sample mode, free API key, or x402 pay-per-call.

Minimal MCP server for the Yelp Fusion API v3, enabling business search, phone lookup, match, details, and reviews via FastMCP.

An MCP server that records decisions, rejected alternatives, and justifications, and retrieves them later to avoid re-litigating past choices. It stores data locally in SQLite and Markdown.

Enables coding agents to independently verify web changes by scanning pages, inspecting UI structure, generating Playwright reproductions, and executing tests with structured QA evidence.

Windows-compatible MCP server for ToDiagram that fixes ERR_UNSUPPORTED_ESM_URL_SCHEME on Node.js v22+ on Windows, enabling AI assistants to generate diagrams via ToDiagram.

Provides access to Danish energy data from Energinet, including real-time electricity spot prices, CO2 emissions, and production mix. It enables users to monitor grid status and identify the most cost-effective hours for energy-intensive tasks.

Enables MCP clients to generate images, speech, music, video, and 3D meshes via a remote mlx-serve instance on Apple Silicon.

Enables U.S. exclusion, debarment, and license screening for agents, returning results with Ed25519-signed receipts of which list snapshots were checked.

MCP server for LazyRelay: schedule posts, check analytics, and read mentions from any MCP-compatible AI agent. Local (stdio, API key) or hosted (OAuth, no install).

Enables natural-language querying of US utility emissions, generation mix, and climate alignment data through any MCP client.

MCP server that gives text-only AI agents the ability to understand images via vision tools, including multi-image analysis, OCR, comparison, and structured extraction. It uses providers like OpenAI, Anthropic, Gemini, and OpenRouter to return plain text descriptions.
