Etsy MCP Server

Feedjolt's MCP server gives AI agents and MCP clients programmatic access to your feedback boards, posts, comments, roadmap, and changelog. Read feature requests, triage and tag feedback, change post statuses, merge duplicates, and publish changelog entries straight from any MCP-compatible client. Built for startups and indie teams who run their feedback loop where they build. Streamable-HTTP transport, API-key auth.

Agent-native forum for the x402/A2A ecosystem. The hosted MCP server exposes the whole forum as tools — threads, comments, votes, USDC bounties (x402 on Base), provider reviews, and search.

Rinkta is a professional-services workspace for agencies and independent teams — tasks, projects, clients, and billable entries in one place. This connector lets your AI assistant search and read your workspace, look up tasks, projects, clients, and entries, and create new tasks and clients on your behalf. Access follows your workspace role: financial data (clients, projects, entries) is only visible to owners, admins, and accountants, and read-only connections never get write access.

One API for Search, Crawling, and Sitemaps

### Deterministic Music Theory for Claude, Cursor, and Autonomous AI Agents Large Language Models (LLMs) frequently hallucinate music theory, leading to incorrect notes, false Roman numerals, and broken voice leading. **THIRI** solves this by providing a deterministic, mathematical music-theory engine (pitch-class-set theory over ℤ/12) directly to your AI. It gives AI assistants precise, reproducible harmonic reasoning in milliseconds, allowing them to write correct musical scores, analyze progressions, and generate playable arrangements. #### 🎷 Key Features: * **Chord Analysis (`analyze_chord`):** Parse any symbol (e.g., `Cmaj7/E`, `G7#11`) to retrieve root, quality, intervals, Roman numerals, and diatonic or chromatic harmonic functions. * **Note Resolution (`resolve_chord`):** Resolve chord symbols to spelled notes (enharmonically correct), frequencies (Hz), MIDI numbers, and scale recommendations. * **Voicing Engine (`generate_voicing`):** Generate instrument-ready voicings (rootless, shell, triad, pad, drop-2, drop-3) and calculate voice-leading scores for transitions. * **Reharmonization (`reharmonize`):** Substitute progressions using classic jazz techniques, including Tritone Substitution, ii-V Insertion, Modal Interchange, Coltrane Changes, and Backdoor cadences. *Ideal for developers building AI music assistants, digital audio workstation (DAW) agents, educational theory tools, and automated composition workflows.*

Persistent memory and shared context for AI coding tools. Two local MCP servers give every AI coding tool a shared, permanent memory of your project across sessions and tools.

Model Context Protocol server that integrates AgentQL's data extraction capabilities.

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.

The terminal AI agents can drive: a cross-platform desktop terminal (macOS/Linux/Windows, MIT) that runs a local MCP server. Spawn tabs/panes, run commands with structured output, read screens and full scrollback, take scrolling screenshots, record sessions with secret redaction, switch identity profiles. Auto-registers with Claude Code / Codex / Gemini CLI on install.
