Arguments

Field	Type	Required	Default	Values	Description

`max_msgs`	`integer`	—	—	—	MaxMsgs caps the number of stored messages; -1 (default) is unlimited.
`name`	`string`	—	—	—	Name is the stream name, unique within the org (alphanumeric, hyphens, underscores).
`num_replicas`	`integer`	—	—	—	Replicas is the number of stream replicas (1–5); this plane runs 1.
`retention`	`string`	—	—	—	Retention is the retention policy: limits (default), interest, or workqueue.
`storage`	`string`	—	—	—	Storage is the storage backend: file (default) or memory.

tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. max_bytes, max_msg_size, max_msgs and num_replicas hold stand-ins that cannot be spelled that way — JSON gives a number, a boolean and a timestamp no placeholder form — so those values are this page's, not the API's. Neither the door nor the operation declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.
