MCP Iceberg Catalog

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

Wet-lab triage for AI binder-design agents. Submit computational protein designs, get back yeast-display enrichment and called hits.

Browser automation and web scraping

Give teams and AI assistants a shared understanding of goals, projects, decisions, and risks.

Playwright MCP server

A neutral, keyless source of the live present for AI agents and software — weather & forecasts, hazards (bushfire, earthquakes, severe weather), air quality, space weather, flights & shipping, cyber risk, rates & macro, and more. Every datapoint carries its source and licence and is Ed25519-signed (optionally Bitcoin-anchored), so a consumer can verify it's authentic and unaltered — verify us, don't trust us.

A Model Context Protocol server that provides time and timezone conversion capabilities. This server enables LLMs to get current time information and perform timezone conversions using IANA timezone names, with automatic system timezone detection.

Template Vault is an AI-native website builder. Connect it once and your AI can generate a complete one-page website from a business brief in under a minute — real running URL, real Vercel deployment, custom domain on Pro+ tier. Six tools: `discover_business_needs` (interview the user before generating), `list_personalities`, `generate_site`, `get_generation_status`, `list_user_sites`, `publish_site`. Quotas tied to the user's Template Vault plan, so MCP calls don't bypass billing. The discovery-first workflow is the unusual bit — most MCP servers expose CRUD tools; ours expose a guided pipeline that makes the AI a better website-builder than a one-shot prompt would. Auth: OAuth 2.1 with PKCE. Works in claude.ai's "Add custom connector" flow with no manual client registration — paste the URL, click Allow, done.

14 utility tools for AI agents: QR code generation, PDF compress/merge/split/convert/unlock, cryptographic hashing (MD5/SHA-1/SHA-256/SHA-512), UUID generation, Base64 encode/decode, secure password generation, IP geolocation, DNS records, SSL certificate check, and WHOIS lookup. Free tier: 1,500 calls/month. No credit card required.

x402 Trust Layer is the trust, security & settlement control plane for autonomous agent payments. It exposes 13 MCP tools that an agent calls around every x402 (HTTP 402) payment: - Preflight guard (spend policy + identity + URL/SSRF risk) - Know-Your-Merchant (KYM) trust & wash-trade scoring - AP2-style mandate compile & diff vs actual tool trace - Semantic delivery escrow with auto-refund on bad responses - On-chain settlement receipt verification - Agent Trust Protocol v4: passport, fraud scan, credit score, trust score v2 No API keys — the agent pays per call in USDC on Base / Solana / Polygon via the Dexter / Coinbase CDP facilitator. Works with Claude Desktop, Claude Code, Cursor, and any MCP client. Live API & dashboard: https://x402trustlayer.xyz/dashboard

Docsie MCP brings your documentation workflow directly into Claude. Create, edit, and publish docs without leaving your AI assistant. Convert videos into structured documentation instantly, run compliance analysis on text, audio, and video content, and use semantic search to find exactly what you need across your knowledge base. Whether you're building product docs, SOPs, or technical guides, Docsie MCP makes it faster and smarter — all powered by AI.

Local guardrail proxy for AI coding agents. Wraps any MCP server (stdio or Streamable HTTP) and blocks destructive tool calls — DROP TABLE, rm -rf, force-push — before they execute. TOFU catalog pinning against rug pulls, plus tool-poisoning and result-injection scanning. Single Rust binary, Apache-2.0.

Remote Streamable HTTP MCP server for AI SRE workflows: server health, alerts, diagnostics, playbooks, approvals, audit history, deploy verification, and safe server inspection. Uses OAuth 2.1 with PKCE.

Search 47,000+ marketing agencies and get AI-matched with fitted agencies, from Pick an Agency. Hosted, public, read-only — no API key required. Tools: search_agencies, match_agencies (the "Get Matched" engine), get_agency. Every result links back to the agency's profile on pickanagency.com.

CoreClaw MCP Server enables AI applications to interact with the CoreClaw platform through the Model Context Protocol (MCP). Once connected, your AI agent can search for scrapers in CoreClaw Store, run them with custom parameters, and retrieve structured data — all through natural language conversations.

A shelf for the HTML your AI coding agent writes. Push an HTML report, dashboard, or spec over MCP — htmlbook stores it, themes it for reading on any device, organizes it by project, and shares it with a link.

### 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.*
