@inbin/mcp
A minimal stdio-to-HTTP proxy for Inbin's Model
Context Protocol surface. Lets stdio-only MCP clients (Claude Desktop,
some Cursor builds, Zed, Cline) talk to Inbin's remote endpoint at
https://api.inbin.dev/mcp.
Install & run
Nothing to install globally. Your MCP client invokes it via npx:
Get an API key from https://inbin.dev/dashboard.
No account yet?
Over the remote endpoint (below) five tools need no key at all. An agent can
create an inbox, use its address, and wait for a verification code:
create_trial_inbox returns an inbox_address at once (it expires after 14 days).
- Use that address wherever a confirmation must be sent.
await_trial_inbox with that exact inbox_address waits up to 60 seconds for the code or link. Call it again if it returns expired.
claim_trial_inbox returns a link for a person to keep the address, and await_trial_inbox_claim and claim_connection_status follow that claim.
This stdio wrapper always sends a key, so it is for the key tools. For the
no-account tools connect straight to https://api.inbin.dev/mcp with no
header. A runnable walkthrough:

What it does
- Forwards each stdin JSON-RPC message to
https://api.inbin.dev/mcp
as an HTTPS POST with your Bearer key.
- Streams the response back to stdout.
- Notifications (messages with no
id) get no reply, per JSON-RPC.
- Concurrent in-flight requests are supported.
Tools exposed
Every Inbin application is an MCP server. With a key, the tools include (ask tools/list for the full set):
list_inboxes: enumerate inboxes in your app
list_events: filter by inbox / status / since; paginated
search_events: substring search over id / subject / from / to
get_event: a single event's parsed JSON + delivery history
query_events: filter, sort, group and aggregate over extracted
records (your inbox as a table)
describe_schema: the current extraction schema
Environment
Remote (recommended)
If your MCP client supports Streamable HTTP transport, skip this
wrapper entirely and connect directly. Without a header you get the five
no-account tools; with a key you get everything:
