Connect bug Agent to any MCP-compatible AI client. File, classify, and manage bugs, feature requests, and more directly from your AI coding assistant. No context switching, no copy-paste — just describe the issue and bug Agent handles the rest. bug Agent runs the hosted MCP server so AI clients can create, query, and manage bug reports, feature requests, enhancements, and more through the Model Context Protocol. Clients connect directly to the hosted Streamable HTTP endpoint. Create a Free account; new workspace owners are taken directly to API-key setup. Returning users can generate a key from Settings → Developers → API Keys.

Use the Prompt Buddy CLI to create, index, and verify local instruction skills. Use the remote MCP server to give AI clients authenticated access to workspace prompt assets. CLI commands create local project state, lock installed skills, and make skill validation usable in scripts and CI. The CLI is the fastest way to bring Prompt Buddy into a code repository. Create or detect local instruction skills, track managed state in lockfiles, and verify skills in CI. Works as \prompt-buddy\ for scripts and \pb\ for daily use.

A MCP server for the Open Library API that enables AI assistants to search for book information.

A Cursor plugin that provides access to Cello, enabling AI assistants to Launch and manage your User Referral and Partner program. This plugin connects your AI assistant to Cello. 1. Open Cursor settings 2. Navigate to Plugins 3. Click Browse Marketplace 4. Search for "Cello" 5. Click Install - Cello Documentation: https://docs.cello.so/mcp/introduction - Report Issues: Contact Cello support at support@cello.so

Give your AI real music theory. THIRI is the deterministic music theory MCP server + API for AI builders — it lets Claude, Cursor, or any MCP agent analyze chords, run roman-numeral analysis, generate voicings, and reharmonize progressions with answers that are computed, not guessed. LLMs hallucinate music theory: wrong notes, fake roman numerals, voicings that don't voice-lead. THIRI is a deterministic engine (pitch-class-set theory over ℤ/12) behind a hosted API — so C7sus4 keeps its suspension, Caug spells C E G, and "Coltrane changes on Dm7 G7 Cmaj7" returns Cmaj7 Ab7 Abmaj7 E7, every time.

Local MCP voice coach with English pronunciation, grammar, fluency, phoneme-level feedback, practice drills, and learner-profile hints. Install via `uvx mcp-server-pronunciation@0.3.0`.

Shop on amazon.in via LLM. Three tools: product search with "cheapest in stock" + "best value" picks, full product details (price, MRP, discount, rating, stock, seller), and Keepa price history chart links. No API keys, direct HTML scraping with retry on bot-check. Install: `npx amazon-in-mcp-server`.

An MCP server for checking and revoking ERC-20 token allowances across multiple blockchains.

Local-first codebase intelligence engine. Gives coding agents structured context packets, indexed code/schema facts, and diagnostics over MCP, backed by a local SQLite store — so agents stop rediscovering your repo with raw grep. Optional Postgres/Supabase awareness and a bundled Claude Code plugin.

MCP server for interactive .NET / ASP.NET Core debugging via netcoredbg. 27 tools: breakpoints (line, function, exception, data), stepping, thread inspection, exception autopsy, hang/deadlock analysis, and request tracing.

AI code quality gate detecting hallucinated packages, phantom dependencies, stale APIs, and AI-specific code defects. MCP Server + CLI + CI/CD integration.

Reduce context usage on file use. Send only unified diffs instead of full files (up to 20-100× fewer tokens), and read large files with targeted `grep`/`sed` instead of full reads (up to 500×). Kernel-enforced path confinement hard-locks the agent to a configured root: no accidental reads or writes outside scope. Standalone for your file access or embed in any MCP server (Rust, Node.js, Python via WASM).

An MCP server that tracks the historical changes of Twitter usernames.

Give your AI coding agents full visibility into your CI test results. The Currents MCP Server connects tools like Cursor and Claude directly to your Currents dashboard, so agents can diagnose flaky tests, pinpoint failures, and act on real execution data -- without leaving your editor. - Query runs, spec files, and individual test results from CI - Surface error trends and performance metrics across your test suite - Manage quarantine rules, webhooks, and project settings programmatically - Let agents fix what's broken using actual test output, not guesswork
