Concierge

A Python SDK for building MCP servers with progressive tool disclosure. Instead of exposing all tools at once, it organizes them into workflow stages and reveals only contextually relevant tools at each step. Supports semantic search mode that collapses 100+ tools into two meta-tools (search_tools and call_tool).

Best When

You have a large number of MCP tools and need to guide agents through structured workflows, or your agents get confused by having too many tools available at once.

Avoid When

Your MCP server has fewer than 10 tools and no need for staged workflows, or you need a non-Python implementation.

Use Cases

  • • Building multi-step agent workflows where tools should appear contextually (e.g., browse then cart then checkout)
  • • Taming large tool catalogs by collapsing them behind semantic search
  • • Adding workflow state management to existing MCP servers with minimal code changes
  • • Enforcing tool ordering so agents follow intended paths through a process

Not For

  • • Simple MCP servers with a handful of tools (overhead not justified)
  • • Non-Python MCP servers (Python-only SDK)
  • • Cases where you want agents to freely access any tool at any time

Known Gotchas

  • ⚠ Progressive disclosure works via tool filtering, not true capability restriction - agents can potentially bypass if they cache tool lists
  • ⚠ Semantic search mode requires specific ProviderType configuration
  • ⚠ Session state requires backend support for distributed deployments
  • ⚠ This is a meta-framework, not a standalone MCP server - you build servers with it
