Run locally for transcripts
π¨βπΌ Our users really want to include their tags in the context as they write
their journal entries. They could just ask the LLM to run the
list_tags tool,
but that's not as efficient. In fact, the host application they're using could
proactively request the resources we expose without any input from the user as
well. Making it both efficient and convenient for the user.In this step, you'll take your first step toward exposing structured data from
your serverβnot just as tool responses, but as first-class resources that
clients can discover and read.
Your challenge
- Declare the
resourcescapability on your server. - Register a simple resource called "tags" that provides information about all
the tags in the database. This resource should be available at the URI
epicme://tagsand return a JSON array of tags.
This is your first taste of the MCP resources system. No need for dynamic
templates or database integration yetβjust get a static resource registered and
returning a simple value.
An example
Use this example as a reference to complete this challenge.
agent.server.registerResource(
'hello',
'hello://world',
{
title: 'Hello',
description: 'A simple hello world resource',
},
async (uri) => {
return {
contents: [
{
mimeType: 'text/plain',
text: 'Hello, world!',
uri: uri.toString(),
},
],
}
},
)
