MCP URL

https://charonprotocol.xyz/mcp

No key: whoami, list_automations, get_automation, list_runs. simulate_task and proposals need a key.

shell

claude mcp add --transport http charon https://charonprotocol.xyz/mcp --header "Authorization: Bearer cagt_<your key>"

Run it once in a terminal, then ask Claude about this automation.

Scopes

Scope	What it allows
read	Read only. Reads this automation's runs, policy, tasks and balances. It can't suggest anything.
propose:limited	Suggest safer changes. Reads, and can suggest: pause, turn a task off, revoke an operator, lower caps, cancel a queued rule change. You sign each one.
propose	Suggest any allowed change. Everything above, and can also suggest: raise caps (at most 2×, at most 0.1 HYPE a day), deposit gas money (at most 0.05 HYPE), lengthen a task's interval, apply a queued change. You sign each one.

Tools

get_proposalA suggestion's status and change.

Charon's manager

Charon's manager watches each automation, explains every run from on-chain facts, and suggests changes as transactions you review. It never signs, holds keys or moves funds.

Findings are public, written from public chain data. Suggestions are visible to the owner only.
Every number comes from code. The wording comes from set templates.
A suggestion goes through the same checks, ceilings and simulation as a connected agent's.
Owners can pause it per automation. If the manager is off, automations keep running.

ChatGPT and claude.ai

ChatGPT connects without a key today, so it reads public data only and can't suggest changes. That changes when Charon supports OAuth.
