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 | $0.03899 | $0.03899 |
| Opus 5 | $0.01950 | $0.01950 |
| Sonnet 5 | $0.00780 | $0.00780 |
| Haiku 4.5 | $0.00390 | $0.00390 |
Grade C, and why
semantic-search-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 11d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Semantic Search MCP Server
An MCP server providing semantic code search for Claude Code using local embeddings.
Project Overview
This server enables natural language code search across codebases. It combines vector similarity search with traditional full-text search using Reciprocal Rank Fusion for optimal results.
Key capabilities:
- Search code with queries like "authentication middleware" or "database connection pooling"
- 165+ language support via Tree-sitter parsing
- Automatic incremental indexing via file watcher
- Zero external API dependencies - all embeddings generated locally

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.
- 11d ago First seen · 402 lines · 3,899 tokens per session scan C 53e9e888ec11
semantic-search-mcp CLAUDE.md is an instructions file published in the GitHub repository adam-hanna/semantic-search-mcp (5 stars, last pushed 8mo ago), licensed MIT. It adds 3,899 tokens to every session, about $0.0195 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 2026-08-31.
