What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a database query by concatenation lib/search.ts:1135
         select word, (${tsqExpr}) as tsq
Builds a file path from a variable packages/kybase-mcp/build-mcpb.mjs:24
  if (!fs.existsSync(path.join(here, required))) {
Secret passed into the image build Dockerfile:12
# Build-time placeholder — real secrets injected at runtime via env
ENV KYBASE_SECRET=placeholder

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add kybase -- npx -y kybase-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "kybase": {
      "args": [
        "-y",
        "kybase-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.kybase]
command = "npx"
args = ["-y", "kybase-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "kybase": {
      "args": [
        "-y",
        "kybase-mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "kybase": {
      "args": [
        "-y",
        "kybase-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: KYBASE_DATA_DIR (Where the embedded database and instance secret live. Defaults to ~/.kybase), EMBEDDING_PROVIDER (Embedding provider for semantic search), OLLAMA_URL (Ollama endpoint for local embeddings. Without any provider, full-text search still works), OLLAMA_MODEL (Ollama embedding model), GOOGLE_API_KEY (Google API key, when EMBEDDING_PROVIDER=google. Sends note text to Google), OPENAI_API_KEY (OpenAI API key, when EMBEDDING_PROVIDER=openai. Sends note text to OpenAI), DATABASE_URL (Use an existing Kybase Postgres instead of the embedded one (migrations are left to the app)). The author declared them in the registry entry; get the values from the project itself.

Kybase — questions

Answers built from our own checks of this server.

Why is there no uptime for Kybase?
Kybase runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package kybase-mcp.
How do I connect Kybase?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls kybase-mcp straight from npm; nothing to host, nothing to sign up for.
Is Kybase open source?
Yes — it is published under the AGPL-3.0 licence, written in TypeScript and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
