20 Python MCP Tools Worth Knowing, From Server Building to Gateways, Security and Eval
MaryamMiradi · x · 2026-11-10
A curated tour of the open-source MCP (Model Context Protocol) tooling ecosystem, listing 20 Python tools by role:
- Building MCP servers: MCP Python SDK (official client/server SDK), FastMCP, mcp-use, mcp-agent.
- Connecting MCP to agents: OpenAI Agents SDK, PydanticAI, LangChain, CrewAI.
- Gateways and routing: ContextForge (gateway + governance + observability), mcp-gateway, MCP Gateway (auth + registry + audit + policy), MCP Proxy for AWS.
- Security and identity: MCP-Scan (tool poisoning and prompt injection scanning), MCP Auth (OAuth), MCP Safeguard (injection/credential/SSRF scanning), MCP Security Gateway Monitor (PII leakage and exfiltration monitoring).
- Testing and production: mcp-eval, Microsoft Agent Framework, AutoGen, MCP Registry Search.
The author notes that running MCP in production means handling permissions, retries, timeouts and bad tool responses, and keeping every tool call within clear limits, and says a benchmark of FastMCP vs mcp-use vs mcp-agent vs ContextForge vs MCP-Scan vs mcp-eval may follow.
