MCP Server for Z.AI - A Model Context Protocol server that provides AI capabilities
headlesson 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.
What it does
Find and compare headless apps (CLI, MCP, API) for agents, with sources, lessons and changes.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http headlesson-mcp https://mcp.headlesson.com/mcp
# 2 — ask your agent for something these tools do
# headlesson_search, headlesson_get, headlesson_whats_new and 1 more
headlesson costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
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.
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 headlesson-mcp https://mcp.headlesson.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
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.
4 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.
Find and compare CLI, MCP, and API apps by task, name, and confirmed axes. Known axis spelling aliases are normalized (licence to license, local_mcp_server to local_mcp, remote_mcp_server to remote_mcp); unrecognized axes are reported as unknown_axes. Private sources use an operator-provided or editorial source label; local paths are not returned as citations. Non-public provenance exceptions are
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | no | Task or product name in English or Japanese; common request words are ignored. |
| where | object | no | Confirmed axis filters: AND across axes, OR inside a value array; known spelling aliases are normalized. |
| axes | array | no | Axes to compare: auth, pricing, license, cli, local_mcp, remote_mcp are useful starting points; licence is normalized to license. |
| sort | object | no | Optional axis ordering before relevance; unknown values remain last. |
| ids | array | no | Explicit app IDs to compare; any missing ID produces an error instead of being silently omitted. |
| limit | integer | no | Maximum app results, from 1 to 20; default is 5. |
Get a recorded app, concept, protocol, usecase, feature, axes or search guide by ID. Private source tuples use non-URL source labels and grouped non-public exceptions; docs/homepage labels are not links. operator_own and lesson.tested retain their values but are operational observations excluded from source-default inheritance.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | Record ID or the special axes/search-guide ID; missing records return nearby ID suggestions. |
| sections | array | no | App sections to return in text and structuredContent; omitted means description, interfaces and six major axes. |
List documented changes since a date, optionally by kind or affected record. Public source URLs remain; private sources use non-URL labels and grouped exceptions.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| since | string | no | Inclusive event-date lower bound in YYYY-MM-DD; omitted uses the previous 90 days, not source confirmation dates. |
| kinds | array | no | Change kinds to include; the array is an OR-list. |
| about | string | no | Affected record ID to filter changes, such as an app or protocol. |
| limit | integer | no | Maximum changes, from 1 to 100; default is 20. |
This content is sent to the headlesson operator. Feedback about headlesson itself is sufficient. Do not include personal information or conversation contents.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| text | string | yes | Feedback to the headlesson operator, 1–2000 Unicode characters; exclude personal information and conversation text. |
| kind | string | no | Report type: comment, worked, failed, missing or tip; receipt does not verify the claim. |
| about | string | no | Optional record ID that the feedback concerns; feedback about headlesson itself needs no product ID. |
| client | string | no | Optional client name only; do not include full User-Agent, account IDs or credentials. |
| model | string | no | Optional model name associated with the report, without conversation content. |
- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install headlesson or to call it, at any volume.
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 0.1.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish headlesson can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
