mcp-server-tool-kit

Minimal stand-in for the Tools Framework (package dynamic-tool-mcp) expected by agentic-assembly-framework. A FastMCP server that dynamically loads tools from .py+.yaml pairs, plus a client satisfying AAF's McpRuntimeAdapter contract (get_session(server_url, bearer_token) -> session.call_tool(id, input)).

Pairs with agent-impl-tool-kit, the sibling stand-in for AAF's Agent Framework (agentic-platform) — together the two satisfy AAF's AgenticPlatformAdapter and McpRuntimeAdapter contracts for local dev.

Run it

pip install -e .
dynamic-tool-mcp --tools-dir tools --host 127.0.0.1 --port 9100

Adding a tool

Drop a matching pair into the tools directory — no restart-time registration:

tools/
├── add_numbers.yaml   # id, description, input_schema, function (default "run")
└── add_numbers.py     # def run(input: dict) -> object

Auth

Set MCP_BEARER_TOKENS (comma-separated) to require a bearer token on every request. Omit it to run with no auth, matching a local-dev assembly.

Client

from dynamic_tool_mcp.client import DynamicToolMcpClient

client = DynamicToolMcpClient()
session = await client.get_session("http://127.0.0.1:9100/sse")
result = await session.call_tool("add_numbers", {"a": 1, "b": 2})
