Free deterministic tools for math, data transforms, dates, text, statistics, finance, and units.
遠端 MCP 伺服器，為助理提供免費的決定性工具目錄，涵蓋數學、資料轉換、日期、文字、統計、金融與單位換算，依 id 與版本執行。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.github.321zz321%2Fcomputefirst/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

}Instructions for Claude Code, Codex, Grok, and other autonomous agents to use ComputeFirst for deterministic computation: search → read the versioned contract → execute. Free, no API key or sign-up. Live-verified catalog: 837 tools (2026-11-05).
Install the Claude Code skill and MCP connection from this repository's marketplace:
Or add the MCP connection alone:
Codex ~/.codex/config.toml:
For Codex skill discovery, copy skills/computefirst/ into .agents/skills/computefirst/ or ~/.agents/skills/computefirst/, preserving references. Client setup and sources cover Claude Code, Cursor, VS Code, generic MCP clients, and plain HTTP.
Read the skill for selection rules, exact requests, limits, and six actual API results. AGENTS.md provides condensed guidance. The full MCP route exposes gateway tools; /mcp/chatgpt offers 40 named operations with smaller limits.
Verify with Node.js 22+ and network access:
The script reads the documented requests/results directly and fails on drift. It also checks discovery and both MCP routes. No dependencies, credentials, or reporting calls. MIT license.

Search tools
Search the ComputeFirst catalog (computefirst.net/tools) with an English task. Returns up to 5 tools (3 by default) with id, version and a 0–1 score; a confident first match includes its input contract. No match: request_tool can ask for one.
limitquery必填include_contractDescribe a tool
Input schema, limits and examples of one ComputeFirst catalog tool, by id and version.
id必填version必填Run a tool
Run one ComputeFirst catalog tool by id and version with its JSON input. Returns the deterministic result and an unmeasured savings receipt. Limits: computefirst.net/docs#limits.
id必填input必填modelversion必填Run tools in one batch
Run 1–20 ComputeFirst catalog tools in one request. Optional bindings fill an input key from an earlier result (JSON Pointer); include_result:false omits an intermediate. Steps after a failed dependency are skipped; nothing is retried automatically. Each success is one execution. Inputs, results and response: 256 KiB each. A factory work budget can skip an item with batch_work_limit; finance and exact decimal power/root/expression tools use the full factory allowance. Send additional factory operations separately. Split refused work; successful items are never retried automatically.
modeloperations必填Read savings
Savings totals, optionally for one model: with a key, the account's measured and estimated totals; otherwise community verified totals. Unmeasured is not zero.
modelSend feedback
Tell ComputeFirst what helped or went wrong (a missing tool fits request_tool). A stable request_id makes retries safe. Leave out secrets and raw data.
message必填category必填request_id必填execution_refRequest a missing tool
Ask for a tool that does not exist yet: the task, optionally example input and output. Optional contact_email (with email_consent:true), only if the person wants one email when it ships. Leave out secrets.
description必填contact_emailemail_consentexample_inputexample_outputSubscribe to new-tool emails
Subscribe an email to new-tool announcements, only when the person asks for them (consent:true). Every email has an unsubscribe link.
email必填consent必填Create a free account (optional)
Only when the person explicitly asks for a free account (consent:true): creates one for their email (unverified) and returns an agent key once, for saved tools, history, personal savings and a higher limit. The person stores the key in their client settings; do not repeat it in the conversation. newsletter:true only if they ask.
email必填consent必填newsletterShow account profile
The signed-in account: keys, privileges and tool-request status. Without a key: signed_in:false and the optional extras.
無需輸入參數。
Show account activity
The account's recent calls and outcomes; pass next as before for older ones. Without a key: signed_in:false.
limitbeforeList saved tools
Tools saved in the account's library (id, version, note). Without a key: signed_in:false and no tools.
無需輸入參數。
Save a tool
Save a tool id and version to the account's library, with an optional note (saving again replaces the note). Without a key nothing is saved.
id必填noteversion必填Remove a saved tool
Remove a tool id and version from the account's library. Without a key nothing changes.
id必填version必填Report model and savings (optional)
Optional, for the person: your model id and, if known, your own estimate of the tokens a call saved (estimated_tokens_saved). Returns its dollar value at public list prices; unknown stays null. A measured comparison adds task_id, baseline_id, baseline, actual, whole_task:true, execution_ref.
