Claude Code configuration

claude mcp add --transport http astranl-counterparty-mcp https://astranl.com/mcp/streamable?profile=counterparty

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add astranl-counterparty-mcp --url https://astranl.com/mcp/streamable?profile=counterparty
