MCPpedia MCP Server

Search, evaluate, and compare 17,000+ MCP servers from the MCPpedia catalog. Every server is scored on security, maintenance, efficiency, documentation, and compatibility — with real CVE scanning and tool poisoning detection.

Tools

Tool	Description
search_servers	Search by keyword, category, or minimum score
get_server_details	Full details: scoring breakdown, tools list, install configs. Pass security: true for a deep security report with CVE/poisoning/injection evidence
compare_servers	Side-by-side comparison across all 5 scoring dimensions
get_install_config	Ready-to-use config for Claude Desktop, Cursor, Claude Code, Windsurf (elicits the client if omitted)
get_trending	Top-rated, most starred, or newest servers by category
get_category_tree	Every category with server counts — call before search_servers to narrow scope
what_changed	Servers rescored since a given ISO-8601 timestamp

Every tool returns both a markdown summary and structured JSON (structuredContent) so MCP clients can render scores/tables natively. List-shaped tools also emit resource_link content blocks pointing at mcppedia://server/{slug} so users can click-to-attach a result.

Resources

URI	Description
mcppedia://trending	Top 20 servers by score
mcppedia://server/{slug}	Full record for one server
mcppedia://category/{name}	Top servers in a category

Install

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "MCPpedia": {
      "command": "npx",
      "args": ["-y", "mcp-server-mcppedia"]
    }
  }
}

Claude Code

claude mcp add MCPpedia -- npx -y mcp-server-mcppedia

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "MCPpedia": {
      "command": "npx",
      "args": ["-y", "mcp-server-mcppedia"]
    }
  }
}

Windsurf

Add to your MCP config:

{
  "mcpServers": {
    "MCPpedia": {
      "command": "npx",
      "args": ["-y", "mcp-server-mcppedia"]
    }
  }
}

Remote (Streamable HTTP)

Run the server with --http to expose it as a Streamable HTTP endpoint (MCP 2025-03-26 transport):

npx mcp-server-mcppedia --http
# Listening on port 8080, endpoint POST /mcp, health GET /healthz

Set a custom port with PORT=3001 npx mcp-server-mcppedia --http. CORS_ORIGIN controls the browser CORS allow-list.

Desktop Extension (DXT)

A manifest.json is included for one-click install in Claude Desktop. Zip the package with dxt pack (from @anthropic-ai/dxt) and distribute the resulting .dxt.

Smithery

A smithery.yaml + Dockerfile are included — deploy as a hosted MCP server at smithery.ai.

How It Works

Your AI Agent  →  MCPpedia MCP Server  →  mcppedia.org/api/mcp  →  Database
   (local)            (local)              (rate-limited, cached)

The MCP server calls the MCPpedia public API — no API keys needed. Your credentials stay safe on the server side.

Transports

Transport	Use case	Command
stdio (default)	Local clients: Claude Desktop, Cursor, Claude Code	npx mcp-server-mcppedia
HTTP/SSE	Remote deployment, shared servers, web clients	npx mcp-server-mcppedia --http

Rate Limits

• 60 requests/minute per IP (no sign-up needed)

Examples

Find the best server for a task

"Find me a good MCP server for working with databases"

The AI calls search_servers with query "database", gets back scored results.

Check if a server is safe

"Is the filesystem MCP server safe to use?"

The AI calls get_server_details with slug: "filesystem", security: true, gets back a full security report with CVE count, tool poisoning detection, injection risk analysis, and evidence.

Compare alternatives

"Compare the Puppeteer and Playwright MCP servers"

The AI calls compare_servers with both slugs, gets a markdown table comparing all 5 scoring dimensions.

Get install instructions

"How do I install the GitHub MCP server in Cursor?"

The AI calls get_install_config with slug: "github", client: "cursor", gets back a ready-to-paste JSON config.

Discover what's trending

"What are the most popular AI/ML MCP servers?"

The AI calls get_trending with category: "ai-ml", sort: "stars".

Security audit workflow

"Audit all my MCP servers for security issues"

The AI calls get_server_details with security: true for each server, compiling a risk report.
