MCP resources reference

Last reviewed: 2026-06-11 08:17 CEST

These are the non-tool resources canary mcp exposes to MCP clients. Tools are documented separately in MCP tools reference.

canary://quote/{symbol}

Live stock / ETF quote resource.

Use this when an MCP client wants to keep watching one equity or ETF quote without repeatedly calling canary_quote. The template is discovered through resources/templates/list.

Example URI:

canary://quote/AAPL

resources/read returns a one-off quote snapshot with the same JSON shape as canary quote AAPL --json, including the enriched headline price, price_source, previous close, change, ranges, volume/average volume, 20-day average volume/dollar volume, price_as_of, stale flags, and optional session_context.

resources/subscribe returns {} and then streams coalesced tick frames through notifications/resources/updated until the client calls resources/unsubscribe or closes the MCP session. Notification payloads embed a JSON frame in params.contents[].text; the frame shape matches canary quote AAPL --watch --json.

Only stock and ETF symbols are supported. Option contract streaming is not exposed as an MCP resource today; use canary_chain or CLI option quotes for option snapshots.
