Claude
Compatibility reference for Claude workspace flows that accept HTTP MCP servers with custom headers.
MCP
Connect PostBridge to MCP clients
Use PostBridge from MCP-capable clients such as Claude, ChatGPT, Codex, and Claude Code. Create the required test or production API key from Settings > API & MCP after signing in and subscribing.
To disconnect, remove or disable PostBridge from the client’s settings page.
PostBridge MCP currently requires Authorization: Bearer YOUR_POSTBRIDGE_API_KEY and a POST JSON-RPC over HTTP client. MCP usage consumes the same workspace wallet and subscription lifecycle, including the wallet auto-reload policy, as SaaS and REST API sends. OAuth/SSE setup is not available yet.
