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 | $0.02436 | $0.02436 |
| Opus 5.5 | $0.00974 | $0.00974 |
| Sonnet 5.5 | $0.00487 | $0.00487 |
| Haiku 4.5 | $0.00244 | $0.00244 |
Grade A, and why
chittymcp 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 5d 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.

What this is
ChittyMCP is the universal MCP aggregator for the ChittyOS ecosystem.
It is a single Cloudflare Worker (src/worker/index.ts) deployed at
mcp.chitty.cc that federates every service, agent, actor, anima, and SDK
MCP under one endpoint via Cloudflare service bindings (no HTTP round-trips).
This is NOT a tool-implementation repo. ChittyMCP is a router; tool logic
lives in a sibling worker in the ChittyEntity monorepo under one of four
canonical directories, keyed by role. Nothing in the URL or the directory
carries a Chitty prefix — the category word already supplies that:
Source layout (chittyentity monorepo)
github.com/CHITTYOS/chittyentity/
├─ chittyagents/<name>/ # service MCPs
├─ chittyactors/<name>/ # autonomous actors that take external actions
├─ chittyanimas/<name>/ # persona / companion entities
└─ chittysdks/<name>/ # shared libraries consumed by the above
Public URL schema
| Role | URL | Example |
|---|---|---|
| Service | <name>.chitty.cc |
notion.chitty.cc |
| Agent | agent.chitty.cc/<name>/ |
agent.chitty.cc/notion/ |
| Actor | actor.chitty.cc/<name>/ |
actor.chitty.cc/dispute/ |
| Anima | anima.chitty.cc/<name>/ |
anima.chitty.cc/casey/ |
| SDK | sdk.chitty.cc/<name>/ |
sdk.chitty.cc/evidence/ |
| Aggregator | mcp.chitty.cc/<name>/mcp |
mcp.chitty.cc/notion/mcp |
No chitty / chittyagent- prefix anywhere in <name> — the subdomain
(service) or path parent (agent / actor / anima / sdk) carries the role.
chittyentity/workers/chittyagent-* is the old source path and no longer
canonical. (The wrangler.jsonc comment claiming <name>.agent.chitty.cc/mcp
is also stale — the live pattern is the table above.)
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.

chittymcp CLAUDE.md is an instructions file published in the GitHub repository chittyos/chittymcp (0 stars, last pushed 5d ago), licensed MIT. It adds 2,436 tokens to every session, about $0.0097 per session on Opus 5.5. 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 2026-08-31.
