mcp-server: Instructions file for Claude Code

CLAUDE.md

mcp-server CLAUDE.md is an instructions file for Claude Code from supavec/mcp-server. It costs 612 tokens per session, scanned A, original, MIT.

A TypeScript MCP server that lets AI assistants retrieve relevant content from Supavec files and list a user's uploaded files. MCP is a standard way to give assistants tools.

In plain words
What is it for?
Use it to build and run the server, authenticate with a Supavec API key, fetch matching file content, list files, or inspect it with MCP Inspector.
Why use it?
It connects an assistant to Supavec's embedding-based file search without requiring the assistant to handle those API operations directly.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Cursor.

This is supavec/mcp-server's own configuration. It tells Claude Code how to work on mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Model Context Protocol (MCP) server that enables AI assistants to interact with Supavec's embeddings API. The server provides two main tools:

  • fetch-embeddings: Retrieves relevant content from Supavec files using embeddings
  • list-user-files: Lists all files uploaded to a user's Supavec account

Commands

Build & Development

# Build the project (compiles TypeScript to build/ directory)
npm run build

# Build and watch for changes during development
npm run watch

# Test the server with MCP Inspector
npm run inspector

# Test the CLI directly
npm run build && node build/index.js --help

Running the Server

# With API key argument
node build/index.js --api-key your_api_key

# With environment variable
SUPAVEC_API_KEY=your_key node build/index.js

# Show help
node build/index.js --help

Architecture

Entry Point (src/index.ts)

  • Handles CLI argument parsing and API key validation
  • Creates and starts the MCP server
  • API key priority: --api-key argument > SUPAVEC_API_KEY environment variable

Core Components

Server Setup (src/utils/server.ts)

  • Creates MCP server instance using @modelcontextprotocol/sdk
  • Configures server with stdio transport for MCP communication
  • Sets up tool handlers

Tool Definitions (src/tools/index.ts)

  • Defines the two MCP tools with their schemas
  • Handles tool execution by calling Supavec API endpoints
  • Returns structured JSON responses to AI assistants

API Layer (src/utils/api.ts)

  • Centralized HTTP client for Supavec API (https://api.supavec.com)
  • Handles authentication via authorization header
  • Provides error handling and type-safe responses

CLI Utilities (src/utils/cli.ts)

  • Parses command line arguments (supports --api-key and --help)
  • Displays help information

Type Definitions (src/types/index.ts)

  • Embeddings: Response structure for embedding queries
  • UserFile: Individual file metadata from Supavec
  • UserFilesResponse: Paginated response for file listings
  • UserFilesRequest: Request parameters for file listings

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
