  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_charts_mweb",
    "arguments": {
      "chain": "litecoin",
      "start": "2026-06-20",

Parameters

Name	Type	Required	Description
`chain`	string — one of: litecoin	yes	Blockchain network. Currently `litecoin`.
`end`	string	yes	Range end (excluded): ISO date (YYYY-MM-DD) or ISO-8601 Z timestamp. Required.
`grain`	string — one of: day, week, month	no	Time bucket: day, week, or month.
`include_current`	boolean	no	Attach live current data (in-progress window / state snapshots). MCP DEFAULTS THIS TRUE for chart tools; pass false explicitly to receive the pre-change response with no `current` key.
`metrics`	array of string — one of: cumulative_balance_atomic_units, mweb_tx_count, net_flow_atomic_units, pegin_atomic_units, pegout_atomic_units	no	Metrics to include; does NOT change cost. Default omits net_flow_atomic_units — request it explicitly if needed.
`start`	string	yes	Range start: ISO date (YYYY-MM-DD) or ISO-8601 Z timestamp. Ranges are half-open [start,end) — end excluded. Required. Max span per grain: day 731d, week 1827d, month 3653d, year 7305d.

Response

The outputSchema is the CLOSED model contract for structuredContent (top-level additionalProperties: false), answer-first fixed key order: source, tool, endpoint, request (echoed arguments), answer (authoritative result summary — answer from this and data), data (the complete result), included/included_digest (full expansion rows + a compact digest, when paid include expansions were served), units, answerable_fields, warnings, citations (complete visible citation array), usage (per-call cost truth), validation, and pagination (cursor/has_more/effective_limit/requested_limit). The single content block is a short plain-text answer card mirroring the same facts (header, Answer, Units, Warnings, Usage, Source). Errors return a plain-text error card and attach NO structuredContent. See How to cite ForceX MCP results.

Notes

Cost: 4 credits. Costs and tier limits match the wrapped Xtract REST endpoint — see get_developer_limits.
Wrapped REST endpoint: /xtract/docs/reference/charts-mweb/ — the full parameter, response, and methodology reference.
Data-retrieval tool: it never creates blockchain transactions, signs messages, publishes content, or changes third-party state (openWorldHint=false, destructiveHint=false). Successful calls consume Xtract credits and record usage on your ForceX account, so readOnlyHint=false.
