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 | $0.05161 | $0.05161 |
| Opus 5.5 | $0.02064 | $0.02064 |
| Sonnet 5.5 | $0.01032 | $0.01032 |
| Haiku 4.5 | $0.00516 | $0.00516 |
Grade A, and why
jinaai-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.

mcp-ts-template: Architectural Standard & Developer Mandate
Effective Date: 2025-07-31 Version: 2.2
Preamble
This document constitutes the official mandate governing all development practices, architectural patterns, and operational procedures for projects originating from the mcp-ts-template. It is the single source of truth for ensuring code quality, consistency, and long-term maintainability. Adherence to these standards is not optional; it is a condition of all development activity.
I. Core Architectural Principles
The architecture is founded upon a strict separation of concerns to guarantee modularity, testability, and operational clarity. These principles are non-negotiable.
1. The Logic Throws, The Handler Catches
This is the immutable cornerstone of the error-handling and control-flow strategy.
Core Logic (logic.ts): This layer's sole responsibility is the execution of business logic. It shall be pure, self-contained, and stateless where possible. If an operational or validation error occurs, it must terminate its execution by throwing a structured McpError. Logic files shall not contain try...catch blocks for the purpose of formatting a final response.
Handlers (registration.ts, Transports): This layer's responsibility is to interface with the transport layer (e.g., MCP, HTTP), invoke core logic, and manage the final response lifecycle. It must wrap every call to the logic layer in a try...catch block. This is the exclusive location where errors are caught, processed by the ErrorHandler, and formatted into a definitive CallToolResult or HTTP response.
2. Structured, Traceable Operations
Every operation must be fully traceable from initiation to completion via structured logging and context propagation.
RequestContext: Any significant operation shall be initiated by creating a RequestContext via requestContextService.createRequestContext(). This context, containing a unique requestId, must be passed as an argument through the entire call stack of the operation.
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.

jinaai-mcp-server CLAUDE.md is an instructions file published in the GitHub repository cyanheads/jinaai-mcp-server (1 stars, last pushed 1y ago), licensed Apache-2.0. It adds 5,161 tokens to every session, about $0.0206 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
