Connect Verified AI Free Tiers and your agent gets 14 tools, among them audit_ai_stack, build_free_workflow, check_api_quota_fit. It answers at https://baipiaoji.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Verified AI free-tier limits, quota comparisons, commercial-use verdicts and zero-cost workflows.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
audit_ai_stack | Audit several AI tools at once: for each one return its verified free-tier limit, whether the free-tier output may be used commercially, any recently verified change to its allowance, and whether the vendor publishes a figure at all. Use th Inputs: tools, lang |
build_free_workflow | Get a complete step-by-step recipe for doing a task entirely on free tiers - which verified free tool to use at each step and what to do with it, in the order you'd actually work. Covers slide decks, video editing, AI video generation, pape Inputs: task, kind, lang |
check_api_quota_fit | Work out which verified free LLM API tiers can actually carry a given workload. Give the expected calls per day and average tokens per call; this divides the officially published limits by that load and reports which providers stay inside t Inputs: requests_per_day, tokens_per_call, lang |
check_commercial_use | Check whether output from an AI tool's free tier may be used commercially, based on the vendor's official terms (verdicts: yes / no / conditional / depends on the model used / not stated). Not legal advice; details and obligations live on t Inputs: tool, lang |
check_free_tier_claim | Fact-check a circulating claim about an AI tool's free tier against what the vendor officially publishes. Returns what the official pages actually say and whether the widely-quoted figure has any official source at all - many do not. Use th Inputs: tool, lang |
compare_free_tiers | Compare the free tiers of AI tools in one category side by side, as structured data rather than prose: what each vendor grants, how it is metered, when it resets, what is never metered, and whether a figure is officially published at all. C Inputs: category, lang |
explain_missing_figure | Explain why this dataset publishes no figure for a given tool. Absence here is a finding, not an oversight: for each listed tool the reason is recorded - the vendor states outright it publishes no number, its official pages contradict each Inputs: tool, lang |
find_free_alternatives | Given a tool whose free tier is not enough (or that you cannot reach), find alternatives in the same category that are entirely free, with their verified allowances and check dates. Use this when a user has hit a wall, cannot access a servi Inputs: tool, works_in_china, lang |
get_category_playbook | Get the decisive question to ask about a category of AI tools before comparing any numbers - which differs by category and is almost never "how much do I get". Video generation turns on what the watermark looks like, design tools on whether Inputs: category, lang |
get_china_ai_rules | Check what applies when publishing AI-generated content to mainland China platforms, and which AI tools are reachable from mainland China without a VPN. Two independent gates matter there: the vendor's terms decide whether you may publish a Inputs: category, lang |
get_free_tier_changes | List recently verified changes to AI free tiers - which vendor changed what and on which date. Vendors do not announce when they cut, rename or restructure a free tier; this log is accumulated from daily re-checks against official pages. Us Inputs: since, days, tool, lang |
get_free_tier_limit | Get the verified free-tier limit of an AI tool: how far the allowance goes, what happens at the wall, the official source page, and the date it was checked. Absence of a tool means no officially verifiable number exists — this dataset publi Inputs: tool, lang |
search_ai_tools | Search a verified directory of 218 AI tools with genuine free tiers. Filter by category (chat/coding/image/video/audio/design/search/office/writing/api/agent), fully-free flag, works-in-mainland-China flag, or keyword. Every verified entry Inputs: query, category, fully_free, works_in_china, tag, lang |
watch_free_tier_changes | Subscribe a webhook to verified free-tier changes. When a watched tool's allowance, wall or commercial terms change (verified daily against official vendor pages), the webhook receives a JSON payload with the changed fields, the current wor Inputs: hook, slugs, key |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://baipiaoji.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
