Fluent MCP

What is Fluent MCP?

Fluent MCP is a modern framework for building Model Context Protocol (MCP) servers with intelligent reasoning capabilities. It provides a two-tier LLM architecture with tool separation, enabling embedded reasoning and reasoning offloading for token and cost efficiency.

How to use Fluent MCP?

Install with pip install fluent_mcp. Use the CLI command fluent-mcp new my_server to scaffold a new server, or create one programmatically using scaffold_server(). Define embedded and external tools, configure an LLM provider, then run the server with server.run().

Key features of Fluent MCP

• Reasoning offloading from consuming LLMs to embedded LLMs.
• Clear separation between embedded tools (internal) and external tools.
• Server scaffolding via CLI or programmatic API.
• Integration with multiple LLM providers (e.g., Ollama).
• Tool registry for registering embedded and external tools.
• Prompt management with tool definitions in frontmatter.

Use cases of Fluent MCP

• Building MCP servers that perform complex multi-step reasoning internally.
• Creating self‑improving AI systems where LLMs can build and register their own tools.
• Reducing token usage and cost by offloading reasoning to smaller, specialized models.
• Hiding complex internal processes behind simple external tool interfaces.
• Managing granular tool access per prompt for improved security.

FAQ from Fluent MCP

What is the two‑tier LLM architecture?

Fluent MCP uses an embedded LLM for internal reasoning and multi‑step tasks, and a consuming LLM (like Claude) that interacts with the MCP server externally.

How are embedded tools different from external tools?

Embedded tools are only available to the embedded LLM for internal use, while external tools are exposed to consuming LLMs through the MCP protocol.

What dependencies are required?

Fluent MCP requires Python. Install it via pip; development dependencies include testing and linting tools (e.g., pytest, flake8, black).

Where does data live?

The README does not specify data persistence; the framework manages tool execution and prompt loading, with data handling defined by individual tools.

What transports or authentication are supported?

The README does not detail transport protocols or authentication methods beyond the MCP protocol integration.
