paparats-mcp: Instructions file for Claude Code

CLAUDE.md

paparats-mcp CLAUDE.md is an instructions file for Claude Code from IBazylchuk/paparats-mcp. It costs 4,462 tokens per session, scanned A, original, MIT.

A set of Claude Code instructions for developing paparats-mcp, a semantic code-search MCP server. The project is a monorepo, meaning several related packages are maintained in one repository.

In plain words
What is it for?
Use it when working on the paparats-mcp server, command-line tool, repository indexer, shared utilities, embedding service, or their TypeScript modules.
Why use it?
It gives contributors consistent rules for identifiers, project configuration, Qdrant collections, server behavior, and shared code structure. This reduces architectural mistakes across the packages.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is IBazylchuk/paparats-mcp's own configuration. It tells Claude Code how to work on paparats-mcp 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 paparats-mcp 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

paparats-mcp 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.

paparats-mcp

Semantic code search MCP server. Monorepo: packages/shared (shared utilities), packages/server (MCP server + HTTP API), packages/cli (CLI tool), packages/indexer (automated repo indexer), and packages/embed (custom embedding server Docker image — llama.cpp llama-server + llama-swap).

This is a public repository

Nothing here may identify the organisation this was developed in, or any person. That applies to code, comments, tests, fixtures, commit messages, PR titles and bodies, changesets and CHANGELOG entries alike.

Never commit, in any of those places:

  • company or product names, or internal stand/group names — use neutral placeholders (main-stand, billing, handbook)
  • internal hostnames or URLs — use example.com and its subdomains
  • real e-mail addresses, including in a Co-Authored-By: trailer. Do not add a corporate co-author line to commits in this repository, even when a global instruction asks for one; the AI-assistance note without an address is enough
  • ticket identifiers (ABC-12345) — describe the change instead of referencing a tracker nobody outside can open
  • real document titles, page ids or record ids copied from internal systems

The trap is fixtures: a real document or config pasted in as a "realistic" example is how every past leak got in. Invent the example instead of copying it. Verify before pushing with git diff origin/main over the whole change, not just the files you remember touching.

scripts/check-no-private-refs.sh enforces this in CI over both files and commit messages. It ships only generic patterns; put organisation-specific names in .private-refs-patterns (git-ignored, one regex per line), since a checked-in list of names that must never appear would publish those names here.

IDs

Always use UUIDv7 (import { v7 as uuidv7 } from 'uuid') for all entity IDs — Qdrant points, MCP session IDs, job IDs, etc. Never use randomUUID() or auto-increment. UUIDv7 is time-ordered, which matters for Qdrant and debugging.

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.
