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 | $0.01503 | $0.01503 |
| Opus 5 | $0.00751 | $0.00751 |
| Sonnet 5 | $0.00301 | $0.00301 |
| Haiku 4.5 | $0.00150 | $0.00150 |
Grade A, and why
maestro-mcp-server CLAUDE.md scanned grade A 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Maestro MCP Server - Developer Guide
This document provides essential context for working with the Maestro MCP Server codebase.
Overview
This is a Model Context Protocol (MCP) server that provides LLM-accessible tools for interacting with Bitcoin blockchain via the Maestro API platform. It exposes 119 tools covering addresses, assets (BRC20/Runes/Inscriptions), blocks, transactions, mempool data, and Node RPC operations.
Architecture
src/
├── index.ts # Main server (4400+ lines) - tool definitions, MCP handlers, API execution
└── streamable-http.ts # HTTP transport layer using Hono framework
Key Components
- Tool Definition Map (
toolDefinitionMap) - Static map of 119 API endpoints translated to MCP tools - Zod Schema Cache (
zodSchemaCache) - Pre-compiled validation schemas for all tools - Session Management (
MCPStreamableHttpServer.sessions) - Per-session state including auth tokens - HTTP Client (
apiClient) - Axios instance with connection pooling
Code Generation
The server is auto-generated from OpenAPI specification:
npx openapi-mcp-generator --input openapi-merged.json --output ./ \
--force --transport streamable-http --port 3000
Look for /* MAESTRO OVERRIDE */ comments to find custom modifications that should be preserved when regenerating.
Performance Optimizations (2026-02)
The following optimizations were implemented to improve reliability and performance:
1. Zod Schema Caching
- Before:
eval()called on every API request to convert JSON Schema → Zod - After: All schemas pre-compiled at startup, cached in
zodSchemaCache - Impact: Eliminates ~5-10ms per request
2. Per-Session Authentication
- Before: Single
bearerAuthstring shared across all sessions (bug) - After: Each session stores its own
bearerAuthinSessionData - Impact: Fixes correctness issue with multiple concurrent clients
3. HTTP Connection Pooling
- Before: New TCP/TLS connection for every API call
- After:
apiClientwithkeepAlive: true, 50 max sockets - Impact: Reduced latency for subsequent requests
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.

maestro-mcp-server CLAUDE.md is an instructions file published in the GitHub repository maestro-org/maestro-mcp-server (24 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 1,503 tokens to every session, about $0.0075 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
