## What locus does, in the publisher's words

Pay-per-use APIs for coding agents. This plugin connects the Locus MCP server and teaches your agent how to use it well: cited web research, paid data and API lookups, and thousands of metered provider endpoints billed to one prepaid workspace credit balance.

One repo, one plugin, many agents. The same plugin installs into Claude Code, Codex, Cursor, Grok, OpenClaw, and any client that speaks the Agent Plugins or Agent Skills open standards.

- MCP server connection to https://api.paywithlocus.com/api/credits/mcp (streamable HTTP). Sign-in is OAuth with browser consent; no keys are stored in configuration.
- The locus skill: operating instructions for the agent covering tool routing, cost quotes, idempotent billing, error recovery, and spend safety.
- The locus-setup skill: full self-serve onboarding, account creation (human sign-up through the OAuth page, or agent-owned accounts via AgentID), capability selection, and a user-requested Stripe funding handoff, so the whole product works from inside the plugin.
