StacklokLabs MCP Development Guide
Quick Reference
Creating Tools
from mcp.server.fastmcp import FastMCP
mcp = FastMCP("skills-mcp")
@mcp.tool()
async def my_tool(param: str) -> str:
"""Tool description for LLM."""
return f"Result: {param}"
Creating Resources
@mcp.resource("skills://{skill_name}")
async def get_skill(skill_name: str) -> str:
"""Return skill content."""
return skill_content
Creating Prompts
@mcp.prompt()
def review_skill(skill_name: str) -> str:
"""Create a prompt to review a skill."""
return f"Please review the skill: {skill_name}"
Running Server
if __name__ == "__main__":
mcp.run(transport="streamable-http")
Context Object
Use Context for logging and progress:
from mcp.server.fastmcp import Context
@mcp.tool()
async def long_task(ctx: Context) -> str:
await ctx.info("Starting task...")
await ctx.report_progress(50, 100)
return "Done"
