Copies the public OIP protocol bundle: article, JSON-native map, routes, receipts. No owner token.

§SELF — protocol specification
## §SELF — OIP protocol specification

**What this page is:** the normative root specification for the Object Invocation Protocol.

**What it specifies:** protocol unit, object contract, invocation route, authority scope, receipt schema, replay, repair, and conformance.

**Read:** https://miscsubjects.com/a/oip-system-browser
**Machine bundle:** https://miscsubjects.com/api/articles/oip-system-browser/bundle?format=markdown
**Live object tree:** https://miscsubjects.com/api/dispatch?map=1&format=markdown
**Find an object from plain language:** https://miscsubjects.com/api/dispatch?ask=<what you want>
**Read one object:** https://miscsubjects.com/api/dispatch?key=<KEY>&format=markdown

**Proof rule:** an action is not proven by intent, description, or a 200. It is proven by the ledger and the OIP receipt for the invocation.

Browser automation

A generated article for one OIP shelf. It lists every operation in this API/CLI/MCP/device/model/core subsystem, links each leaf article, and gives the ledger path for proof.

This page is the operating article for one build subsystem. It is generated from live directory rows. If a task belongs to this subsystem, scan the operations below, open the matching capability article, run only the exact object named there, and verify by receipt.

Kind: device. Capabilities: 9. Machine system map: /api/dispatch?map=BROWSER&format=markdown. Root: /a/oip.

Operations

BROWSER_PLAYWRIGHT

Run a Playwright CLI command on the Mac (npx -y playwright …). g. "screenshot https://x.com /tmp/x.png". First run downloads browsers (~2 min). For full browser automation absorb the playwright MCP server via MCP_PROBE Use when: you need to browser playwright Arguments: the playwright arguments, e. Human article: /a/oip-capability-browser-playwright. Machine doc: ?key=BROWSER_PLAYWRIGHT&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_PLAYWRIGHT.

BROWSER_USE

Run the browser-use agent (AI browser driver). NOT INSTALLED YET — pip3 install --user browser-use + an API key in the Mac env makes this row live Use when: you need to browser use Arguments: task. Human article: /a/oip-capability-browser-use. Machine doc: ?key=BROWSER_USE&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_USE.

BROWSER_MARKDOWN

Get the markdown of a URL via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url}. Returns the rendered markdown Use when: "fetch as markdown <url>" or "what does <url> say" Arguments: see content. Human article: /a/oip-capability-browser-markdown. Machine doc: ?key=BROWSER_MARKDOWN&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_MARKDOWN.

BROWSER_SCREENSHOT

Get a PNG screenshot of a URL via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url, screenshotOptions?}. Returns binary PNG Use when: "screenshot <url>" Arguments: see content. Human article: /a/oip-capability-browser-screenshot. Machine doc: ?key=BROWSER_SCREENSHOT&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_SCREENSHOT.

BROWSER_PDF

Render a URL as PDF via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url}. Returns binary PDF Use when: "save <url> as PDF" Arguments: see content. Human article: /a/oip-capability-browser-pdf. Machine doc: ?key=BROWSER_PDF&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_PDF.

BROWSER_LINKS

Extract all links from a URL via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url} Use when: "what links does <url> have" Arguments: see content. Human article: /a/oip-capability-browser-links. Machine doc: ?key=BROWSER_LINKS&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_LINKS.

BROWSER_SCRAPE

Extract structured data by selectors via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url, elements:{selector}]} Use when: "scrape <selector> from <url>" Arguments: see content. Human article: [/a/oip-capability-browser-scrape. Machine doc: ?key=BROWSER_SCRAPE&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_SCRAPE.

BROWSER_JSON

Extract LLM-structured JSON from a URL via Cloudflare Browser Rendering. $1=account_id, $2=JSON body {url, prompt?, response_format?} Use when: "pull <fields> as json from <url>" Arguments: see content. Human article: /a/oip-capability-browser-json. Machine doc: ?key=BROWSER_JSON&format=markdown. Invocation history: /api/invocations?object_id=BROWSER_JSON.

BROWSER_FETCH

system
The OIP article layer is generated from live directory rows, so it documents the objects that actually run the reference implementation.
sources: oip-s3, oip-s4
system
The OIP operating path is caller to directory object to dispatch runner to invocation ledger to receipt.
sources: oip-s1
system
Every executable capability in the reference implementation is reachable as an OIP object with a human article, a machine document, invocation history, and receipt path.
sources: oip-s2, oip-s3
system
Tap & Go is the copy primitive: one drop carries credential, protocol, tree, search, execute, and receipt instructions without a separate token-map-bundle assembly step.
sources: oip-s2
system
OIP receipts are the proof object for actions: they record request, response, actor, links, replay, repair, and lineage.
sources: oip-s2, oip-s5
