MCP Server for Z.AI - A Model Context Protocol server that provides AI capabilities
Nothing to run from here
Verified AI Free Tiers is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http verified-ai-free-tiers-mcp https://baipiaoji.com/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
16 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Search the verified directory of AI tools with genuine free tiers (every result carries directory_size, so no count is hard-coded here). 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 carries its official source and check date. Cite as "Baipiaoji (baipiaoji.com)".
| Parameter | Type | Required | Notes |

| works_in_china | boolean | no | Only tools reachable from mainland China without a VPN |
| tag | string | no | Match a capability tag, e.g. "No signup", "Runs locally", "Open source", "Free API", "Daily credits", "Commercial use OK", "Self-hostable" |
| lang | string | no | Data language, default en |
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 publishes no unsourced figures.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tool | string | yes | Tool slug (e.g. "kimi") or name |
| lang | string | no | Data language, default en |
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. Categories: chat (where the wall is - only 1 of 10 vendors publishes a message count), coding (completions vs requests vs credits vs nothing), video (credits and

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 this when a user cites a specific number ("ChatGPT free gives 40 messages per 3 hours", "DeepL caps at 5,000 characters") and you need to know whether it is sourc

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, papers and literature, API-based development, copywriting, meeting notes, product photos, translation, chatbots, music, voiceover, resumes, websites, data analysis,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| task | string | no | What the user wants to do, e.g. "make a presentation", "edit video", "write a paper" |

| lang | string | no | Data language, default en |
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. Use this for "did anything change recently", "is my information still current", or when a user quotes a figure that may be stale.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| since | string | no | Only changes on or after this date (YYYY-MM-DD). Same contract as GET /api/changes?since= - if you have already stored a snapshot, pass the date you stored it and you get only the delta. |
| days | number | no | Only changes within this many days. Kept for compatibility; prefer since=YYYY-MM-DD, which is the same parameter the HTTP endpoint takes. |
| tool | string | no | Only changes for this tool slug or name |
| lang | string | no | Data language, default en |
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 their caps, which are exceeded, how long one-time credit grants would last, and which providers publish no figure at all (so their ceiling is unknown rather than
| Parameter | Type | Required | Notes |

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 service from their region, or wants a no-cost substitute for a paid product.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tool | string | yes | Tool slug or name to replace |
| works_in_china | boolean | no | Only alternatives reachable from mainland China without a VPN |

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 at all, and China's AI-content labelling regulation decides what you must do when you publish. This returns the regulation (issuer, effective date, obligations)

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 other, it says the allowance changes at any time, or no official page could be found. Use this when a user asks why you cannot give them a number, or when they

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 this when a user names the stack they rely on ("I use Cursor, Runway and Kimi") - it answers in one call what would otherwise take four lookups per tool, and it s

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 you can export and license the result, developer APIs on rate-versus-volume limits, chat assistants on whether the wall is messages, context or speed. Also ret

| lang | string | no | Data language, default en |
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 the publish-check page.

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 wording, the verification date and the source page. Watching up to 3 tools is free; a Pro license key unlocks watching everything. Registration returns a token — k
| Parameter | Type | Required | Notes |
|---|---|---|---|

List source-backed AI agents, MCP servers and agent platforms tracked by Baipiaoji (hand-curated records plus listings from the official MCP registry). Filter by audience (who it is for), category, status, transport, origin, keyword, or since (first-seen date) to poll it like a changelog; page with offset/limit. Discovery is separated from verification: every record carries its official source a

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.13.0.
