MCP Marketplace MCP Server

MCP Marketplace is a hosted MCP server that exposes the full MCP Marketplace catalog as tools you can call directly from Claude Desktop, Claude Code, Cursor, Codex, or any other MCP-aware client. Find servers by topic, get install configs, compare candidates, and evaluate creators without leaving the conversation.

## Tools

- **search_servers** — find MCP servers by keyword or natural-language query, filter by category, transport, and pricing. Results include security_score, critical_findings count, has_critical_findings boolean, pricing, and install readiness. - **get_server** — full detail for a slug: description, install commands for Claude Code / Codex / Cursor, setup_requirements (env vars extracted from README), security.critical_findings, tool_names, and pricing. - **similar_to** — given a reference slug, return semantically-similar servers via shared embedding space. Enables 'like X but safer' or 'like X but free' follow-ups. - **recently_added** — time-windowed feed of recently-approved servers. Supports optional N-day cutoff and free-only filter. - **creator_profile** — all servers by one creator plus aggregate trust stats (total, avg security score, critical-finding count, grade distribution). Matches on display name or GitHub username. - **compare** — side-by-side of 2-5 servers on security, pricing, mode, tool count, and install availability. Returns explicit 'safest' and 'cheapest' highlights with honest tie-breakers. - **list_categories** — 16 marketplace categories with live server counts.

## How it works

Connects over Streamable HTTP. No authentication required — the catalog is public. Rate-limited per IP (60/min burst, 2000/day sustained). Results are served from a 24-hour cache that busts immediately on catalog writes.

## Example prompts
