Core Model Context Protocol (MCP) Engineering Capabilities
- Production Python (`FastMCP`) & TypeScript MCP Servers: Architecting MCP servers over `stdio`, Server-Sent Events (SSE), and Streamable HTTP transports with strict JSON Schema tool definitions, resources, and reusable prompt templates.
- OAuth 2.1, RBAC & Tenant-Scoped MCP Security: Enforcing per-user OAuth 2.1 tokens, fine-grained permission scopes, human-in-the-loop confirmation gates for mutating tools, and immutable audit logging.
- Legacy System MCP Wrappers: Bridging FileMaker, Salesforce, PostgreSQL, Jira, GitHub, and internal REST/gRPC APIs into clean, context-efficient MCP tools.
Frequently Asked Questions
How do you prevent an MCP server from overflowing the LLM context window?
I design paginated, filterable MCP tools with concise structured summaries and lazy resource URIs so agents retrieve only the exact records and fields required for the current reasoning step.
