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 | $0.05694 | $0.05694 |
| Opus 5 | $0.02847 | $0.02847 |
| Sonnet 5 | $0.01139 | $0.01139 |
| Haiku 4.5 | $0.00569 | $0.00569 |
Grade A, and why
agent-hub-mcp 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 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.
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.

CLAUDE.md - Agent Hub MCP Developer Guide
This file provides guidance to Claude Code (claude.ai/code) when working with the Agent Hub MCP codebase.
Quick Start
1. Install & Build
pnpm install
pnpm run build
2. Configure Claude Code (stdio - Recommended)
Add to your Claude Code settings:
{
"mcpServers": {
"agent-hub": {
"command": "node",
"args": ["/path/to/agent-hub-mcp/dist/index.js"],
"env": {
"AGENT_HUB_DATA_DIR": "/path/to/.agent-hub"
}
}
}
}
For development with tsx:
{
"mcpServers": {
"agent-hub": {
"command": "tsx",
"args": ["/path/to/agent-hub-mcp/src/index.ts"]
}
}
}
3. Test Multi-Agent Collaboration
- Open multiple Claude Code instances in different projects
- Register each agent with
mcp__agent-hub__register_agent - Use messaging and context sharing tools
Common Commands
pnpm test # Run test suite
pnpm run dev # Start HTTP server (port 3737)
pnpm run lint # Check code quality
pnpm run coverage # Test coverage report
IMPORTANT: Multi-Agent Collaboration System
You are part of a collaborative multi-agent system! The Agent Hub MCP enables communication between multiple Claude Code instances working on different projects.
On Session Start:
-
Register with the hub:
- Use
mcp__agent-hub__register_agentwith project-based ID - Notify user: "Connected to Agent Hub as [agent-id]"
- Use
-
Stay synchronized:
- Use
synctool periodically to get messages, workload updates, and hub changes in one call - Inform user of any pending collaboration work
- Example: "📬 You have 3 messages from frontend-agent about API changes"
- Use
-
Share your work context:
- When making significant changes, proactively notify other agents about relevant updates
- Use feature tools to track progress and share context within project boundaries
During Work:
- Be proactive about collaboration: Check for messages when working on interfaces, APIs, or shared components
- Announce major changes: Inform other agents about breaking changes or new features
- Respond to direct questions: Other agents may send questions via messages
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.

agent-hub-mcp CLAUDE.md is an instructions file published in the GitHub repository gilbarbara/agent-hub-mcp (32 stars, last pushed 12mo ago), licensed MIT. It adds 5,694 tokens to every session, about $0.0285 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 2026-08-30.
