Add your own

If a service is not on the list, you can add it yourself. One command:

console

$ lanes link connect custom thing --connector http --auth api-key --auth-header X-Api-Key \
    --base-url https://api.example.com/v1 --openapi https://api.example.com/openapi.json \
    --profile personal --workspace local

Leave out a value it needs and it asks.

The two choices

A provider is exactly two decisions: how the service is reached, and how you prove who you are.

`--connector`	For
`mcp`	Any MCP server
`http`	Any REST API with an OpenAPI description
`imap`	Any mailbox
`dav`	Any CalDAV or CardDAV server
`fs`	Any folder on this machine

`--auth`	For
`none`	Anything public
`bearer`	A token sent as `Authorization: Bearer`
`api-key`	A key in a header you name with `--auth-header`
`header`	Any other fixed header
`basic`	A username and password
`oauth`	A browser sign-in, where the vendor supports registration
`strategy`	A handshake that needs code, like bunq's

Both lists are closed. Everything else about a provider is data hung off the pair, which is why adding one takes no code.

What it writes

A fifteen-line YAML manifest in ~/.lanes-link/data/<profile>/providers.d/. That is the same kind of declaration every built-in provider is, and it is yours to edit from there:

YAML

id: thing
name: Thing
connector:
  kind: http
  base_url: https://api.example.com/v1
  openapi: https://api.example.com/openapi.json
auth:
  kind: api-key
  header: X-Api-Key

Capabilities are discovered rather than written: from the vendor's own MCP server, or from the OpenAPI document. There is nothing per-endpoint to declare.

Because it belongs to the profile, a manifest in one profile is invisible to another, and a deployed endpoint serves your custom providers the same way it serves the built-in ones.

Where to go next

Creating a provider writes one by hand, including the cases that need more than the two lists above.
Connectivity coverage is the honest account of which combinations work, which are closed on purpose, and what none of them reaches yet.

Next: Add it to your agent.
