Set Up Knowledge Base

Add semantic search over markdown documents to an MCP project using the Waniwani KB API (client.kb).

Prerequisites

• Project must already be initialized (no {{MCP_NAME}} placeholders)
• @waniwani/sdk must be installed
• WANIWANI_API_KEY must be set in the environment

Steps

1. Detect MCP name

Look in lib/ for the directory that isn't shared — that's the MCP name. Store as {MCP_NAME}.

2. Create knowledge directory

Create lib/{MCP_NAME}/knowledge-base/knowledge/ directory.

Ask the user: "Do you have .md files to add to the knowledge base, or should I create an example file?"

If no files provided, create lib/{MCP_NAME}/knowledge-base/knowledge/example.md:

# Example Knowledge Base

## What is this?

This is an example knowledge base entry. Replace this file with your own .md files containing information you want your AI assistant to be able to search through.

## How does it work?

Each .md file is split into chunks by H2 headings. The H1 title provides context for each chunk. Run `bun run kb:ingest` to upload your knowledge files to the Waniwani API.

3. Create the ingestion script

Create scripts/kb-ingest.ts (create scripts/ directory if it doesn't exist):

import { readdir, readFile } from "node:fs/promises";
import { join } from "node:path";
import { waniwani } from "@waniwani/sdk";

const knowledgeDir = join(import.meta.dirname, "../lib/{MCP_NAME}/knowledge-base/knowledge");

const mdFiles = (await readdir(knowledgeDir)).filter((f) => f.endsWith(".md"));
console.log(`Found ${mdFiles.length} knowledge file(s)`);

const files = await Promise.all(
  mdFiles.map(async (filename) => ({
    filename,
    content: await readFile(join(knowledgeDir, filename), "utf-8"),
  })),
);

const client = waniwani();

console.log("Ingesting files into knowledge base...");
console.log("Files land in the agent's draft. Publish it in the WaniWani app to make them live.");

const result = await client.kb.ingest(files);
console.log(`Done: ${result.chunksIngested} chunks from ${result.filesProcessed} files`);
