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 | $0.00770 | $0.00770 |
| Opus 5 | $0.00385 | $0.00385 |
| Sonnet 5 | $0.00154 | $0.00154 |
| Haiku 4.5 | $0.00077 | $0.00077 |
Grade A, and why
mcp-christensen 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 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.
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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md - Christensen MCP Server
Project Overview
This is a Clayton Christensen persona agent implemented as an MCP server. It provides strategic advisory tools that apply disruption theory, jobs-to-be-done, and capabilities analysis to business decisions.
Quick Commands
# Build the project
npm run build
# Run the MCP server (for testing)
npm start
# Run validation tests
npm test
# Watch mode during development
npm run dev
# Test with MCP Inspector
npm run inspector
Architecture
MCP Server Pattern
This is a prompt-shaping MCP server, not a logic server. Tools generate structured prompts and context that guide Claude's reasoning, rather than returning deterministic outputs.
User Decision → MCP Tool → Structured Prompt + Framework Context → Claude → Analysis

- get_framework - Reference framework details and questions
Development Guidelines
Modifying the Persona
Edit src/personas/christensen.yaml to change:
- Voice characteristics and phrases
- Framework definitions and questions
- Validation markers
- Sample responses
The persona is loaded at runtime, so changes to the YAML don't require recompilation (but do require server restart).
Adding Frameworks
- Create
src/frameworks/new-framework.ts - Export diagnostic questions, prompts, and voice phrases
- Add to
src/frameworks/index.tsbarrel export - Update tool implementations to include new framework
Testing Changes
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.

mcp-christensen CLAUDE.md is an instructions file published in the GitHub repository m2ai-mcp-servers/mcp-christensen (2 stars, last pushed 7mo ago), licensed MIT. It adds 770 tokens to every session, about $0.0038 per session on Opus 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.
