chittymcp CLAUDE.md

chittymcp CLAUDE.md is an instructions file for coding agents from chittyos/chittymcp. It costs 1,259 tokens per session, scanned A, original, MIT.

Repository instructions for ChittyMCP, a Cloudflare Worker that routes requests to several ChittyOS MCP services. An MCP service lets an AI assistant call external tools; this repository handles routing rather than implementing those tools.

In plain words
What is it for?
Use them when adding or wrapping a service MCP, onboarding a service, or changing the ChittyMCP aggregator.
Why use it?
They show developers which documents and source files define the system, and which older directories should generally be left alone.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

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.

Security

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 4d 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 chittyagent-* service 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 each chittyagent-<name> worker (separate repo: github.com/CHITTYOS/chittyentity/workers/chittyagent-<name>).

Canonical artifacts (read these first)

Artifact Purpose
CHARTER.md Aggregator topology + scope
docs/MCP-SOP.md Canonical SOP for adding/wrapping any service MCP
docs/ONBOARDING.md Step-by-step add-to-aggregator procedure
docs/agent-registry-triage.json Live triage of which services are deployed
wrangler.jsonc Live service-binding list
src/worker/index.ts The aggregator itself (353 LOC, data-driven)

Legacy directories (DO NOT TOUCH unless migrating)

The following are historical Node-based MCP implementations from before the CF Worker aggregator was introduced. They are NOT the live system:

  • src/servers/ — old unified-server.js, evidence-server.js
  • src/core/, src/integration/, src/tools/ — old modular Node MCP stack
  • mcp-evidence-server/, mcp-unified-consolidated/, services/mcp-exec/
  • mcp-chittyconnect/, mcp-http-chronicle/, mcp-gateway-chatgpt/
  • casey-offer.js, mcp-handler.js, mcp-project-sync.js

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.
