Measured tools (10)

• list_calculators

  List available calculators, optionally filtered by category

  Parameters:

  • category — string — Filter by category (e.g., 'finance', 'math')

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_calculator_schema

  Get the input schema for a specific calculator

  Parameters:

  • calculator (required) — string — Calculator slug

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• calculate

  Run a calculation and get results + prefilled URL

  Parameters:

  • calculator (required) — string — Calculator slug
  • inputs (required) — object — Calculator input values
  • strict — boolean — If true, reject invalid or unknown input fields instead of dropping them

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• generate_prefilled_url

  Generate a prefilled URL without running calculation

  Parameters:

  • calculator (required) — string — Calculator slug
  • inputs (required) — object — Input values for URL
  • strict — boolean — If true, reject invalid or unknown input fields instead of dropping them

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• calculate_cas

  Evaluate one or more headless CAS expressions server-side (MCP-only numeric mode). Unsupported expressions return a GUI handoff link.

  Parameters:

  • strict — boolean — If true, reject unknown fields and malformed expressions instead of dropping them
  • expression — string — Single CAS expression to evaluate
  • expressions — array — Optional ordered list of CAS expressions to evaluate in one isolated context (supports assignments across the batch)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• calculate_cas_headless

  Alias of calculate_cas. Headless MCP-only CAS evaluator; if unsupported features are requested, returns GUI handoff details.

  Parameters:

  • strict — boolean — If true, reject unknown fields and malformed expressions instead of dropping them
  • expression — string — Single CAS expression to evaluate
  • expressions — array — Optional ordered list of CAS expressions to evaluate in one isolated context (supports assignments across the batch)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• create_session

  Create a new interactive session for any calculator and return the session URL

  Parameters:

  • calculator (required) — string — Calculator slug
  • metadata — object — Optional session metadata

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_session_state

  Retrieve the current field values, computation transcript, and pending message queue for an active session

  Parameters:

  • session_id (required) — string — Session UUID

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• push_session_action

  Push actions into a session's message queue (set fields, submit computation, trigger plot, etc.)

  Parameters:

  • session_id (required) — string — Session UUID
  • actions (required) — array — Array of SessionAction objects to push to the browser

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• close_session

  Close a session and optionally persist a snapshot of its final state

  Parameters:

  • session_id (required) — string — Session UUID
