Overview

AI-generated overview

A hosted MCP endpoint offering 84 small deterministic utilities for dates, business days, text, URLs, colors, units, hashing and lookups.

What you can do
Thousand API is a remote MCP server that bundles many narrow utility tools behind one endpoint. It covers date and calendar work (holidays, business-day arithmetic, timezone and cron scheduling), text processing (HTML-to-text, token estimation, chunking, PII masking, diffs, similarity), URL and network checks (page metadata, redirect resolution, health checks, IP info, postal codes, exchange rates), conversions (units, colors, Markdown to HTML, QR codes) and small security helpers (JWT decoding, hashing). Utility tools let the assistant search the tool catalog, fetch a tool's schema, check quota usage and run diagnostics, and a batch tool chains up to ten tool calls in one request.
When to use it
Useful when an assistant needs reliable, repeatable calculations rather than model guesses: business-day deadlines, holiday checks, timezone conversions, token budgeting before sending long text, text diffs, URL inspection or unit and color conversions. It is a convenience bundle, so it is worth adding when several of these small tasks come up often.
Requirements
A remote streamable HTTP endpoint; no local runtime or package install. Requires an API key sent in the x-api-key header, obtained from the provider's dashboard. Network access to the provider's endpoint is needed, and usage counts against a plan with a monthly quota.
Before you install
The API key is a secret sent in the x-api-key header; keep it out of shared logs and prompts. Usage is metered against a monthly quota, and exceeding it returns a rate-limit error. Requests, including URLs, text and any data passed to tools, go to a third-party service. The JWT tool decodes without verifying signatures, and the PII masking and token estimation tools are heuristic, not exact.

Installation

In SourceWeft

  1. Open Thousand API in the dashboard and add it to a workspace.
  2. Connect x-api-key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.thousand-api%2Fthousand-api/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

data.execute_batch

Execute Batch

[data] 【複数ツール連続の前に検討】tools:[{id,tool,args}] で MCP ツールを最大10件順次実行。{{stepId.field}} で前ステップ結果を参照。関連ツール3〜5本を個別呼び出しすると往復3〜5回+ツール呼び出しオーバーヘッドが重複するが、execute_batch で1回にまとめコンテキスト消費を大幅削減(概算)。Examples: (1) 今日の日時→祝日→為替 tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}] (2) JSON検証→マージ→統計 tools:[validate:data.validate_json,merge:data.merge_json,stats:data.calc_stats] (3) スラッグ→Base64→HMAC tools:[slug:text.generate_slug,b64:convert.base64,hmac:security.generate_hmac]。詳細は tool-catalog の execute_batch_presets 参照 / Prefer before chaining MCP tools: run up to 10 tools via tools:[{id,tool,args}] with {{stepId.field}} refs. Calling 3-5 related tools individually costs ~3-5 round trips plus repeated tool-call overhead; execute_batch combines them into one call, cutting context usage significantly (approx.). Ex1 today→holiday→rate: tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}].
