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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03286 | $0.03286 |
| Opus 5 | $0.01643 | $0.01643 |
| Sonnet 5 | $0.00657 | $0.00657 |
| Haiku 4.5 | $0.00329 | $0.00329 |
Grade C, and why
zulipchat-mcp CLAUDE.md scanned grade C with 1 finding 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 10d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Current Status (v0.7.3-beta.1)
Install: uvx zulipchat-mcp --zulip-config-file ~/.zuliprc
Project Overview
ZulipChat MCP Server v0.7.3-beta.1 is a Model Context Protocol (MCP) server that enables AI assistants to interact with Zulip Chat workspaces. The project uses FastMCP framework with DuckDB for persistence and async-first architecture.
Essential Development Commands
Environment Setup
# Install dependencies. Never use pip; this project uses uv.
uv sync
# Run the MCP server locally
uv run zulipchat-mcp --zulip-config-file ~/.zuliprc
# Quick run via uvx
uvx zulipchat-mcp
Testing & Quality Assurance
# Run tests (60% coverage gate)
uv run pytest -q
# Skip slow/integration tests for faster feedback
uv run pytest -q -m "not slow and not integration"
# Full coverage report
uv run pytest --cov=src
# Linting and formatting
uv run ruff check .
changed_py=$(git diff --name-only -- '*.py')
[ -z "$changed_py" ] || uv run black --check $changed_py
uv run mypy src
# Security checks (optional)
uv run bandit -q -r src
uv run safety check
Development Testing
# Test connection to Zulip (uses installed package; safe inside or outside the repo)
uv run python -c "from zulipchat_mcp.config import ConfigManager; from zulipchat_mcp.core.client import ZulipClientWrapper; c = ZulipClientWrapper(ConfigManager()); print('Connected:', c.identity_name)"
# Import validation
uv run python -c "from zulipchat_mcp.server import main; print('OK')"

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.

zulipchat-mcp CLAUDE.md is an instructions file published in the GitHub repository akougkas/zulipchat-mcp (27 stars, last pushed 1mo ago), licensed MIT. It adds 3,286 tokens to every session, about $0.0164 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
