# Streaming and MCP transport

> AgentWeb MCP Streamable HTTP, streaming response, error recovery, retry, and rate-limit behavior for agents.

AgentWeb's runtime endpoint at `https://mcp.agentweb.us/mcp` uses MCP Streamable HTTP. Public tool metadata is available before authentication; execution requires scoped credentials.

## Transport

`POST https://mcp.agentweb.us/mcp` follows the MCP Streamable HTTP specification, including standard headers such as `mcp-session-id`, `mcp-protocol-version`, and `Last-Event-ID`. Unauthenticated callers receive one-link onboarding JSON; use `/.well-known/mcp/tools.json` for unauthenticated tool metadata. Tool calls finish with a typed JSON result containing status, verification, receipt, or a structured failure.

Long-running map builds are not streamed: `request_map` returns a request ID, and agents poll `agentweb_map_status` for progress.

## Error recovery

Structured errors include an error code, human-readable message, and retryability. Rate-limited responses return a `Retry-After` header; agents should honor it and avoid retrying irreversible actions without a fresh `Idempotency-Key` and verification state.
