      "Caplight" as the name and https://platform.caplight.com/mcp as the URL, click Add, then Connect and

  note: >-
    Caplight documents that no API key is needed for the MCP server — only a Caplight account. Access is
    authorized over OAuth 2.1 authorization code + PKCE (S256) with dynamic client registration.

  note: >-
    tools/list requires an authenticated OAuth access token, so the live tool names and inputSchemas
    could not be enumerated anonymously. Caplight publishes no llms.txt and no tool-name list, so the
    tool names below are NOT recorded — only the capability areas Caplight itself documents. Input
    schemas require authenticated introspection.

  - MarketPrice price history

positioning: >-
  Caplight distinguishes the two surfaces explicitly: the REST API is for programmatic machine-to-machine
  access (scheduled jobs, data pipelines, embedded widgets) while the MCP server is optimized for
  interactive AI agents that call tools in order and synthesize multi-step research. Caplight states it
  processes only the tool calls the LLM requests and has no access to chat sessions.
