opointo

Registry code: b86cd59dccb46c12

opointo turns a React Native / Expo app designed in a browser into a real project with native UI on both platforms: Liquid Glass on iOS 26, Material 3 Expressive on Android. Free lookup tools cover which component to use, its props, the provider order, theme tokens and the runtime rules, and check_snippet catches code that will render blank. Paid tools (licence key sent as a Bearer token) emit an app or a screen, install components, verify the result and update it later. find_component is the place to start before hand-rolling a UI control, because iOS often already ships one.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

get_provider_tree reads open 3h ago
The exact app-root provider nesting these components require, in the order that works. Getting it wrong fails at runtime, not at compile time. Pass the components in use to see which providers each one needs.

mcp-tool
{ "type": "object", "properties": { "components": { "type": "array", "items": { "type": "string" }, "description": "optional slugs in use" } } }
arguments 12 lines
get_rules reads open 3h ago
The runtime rules for this catalog: the mistakes that make a component render blank or wrong with no warning, no error and no red box (on iOS, mostly native Liquid Glass). Pass a slug to scope them to one component, and a platform to get only the rules that hold there. Relevant before writing animation or layout code around one of these components.

mcp-tool
{ "type": "object", "properties": { "slug": { "type": "string", "description": "optional — omit for catalog-wide rules" }, "platform": { "enum": [ "ios", "android" ], "type": "string", "description": "optional — omit for the rules on both platforms" } } }
arguments 17 lines
get_theme_tokens reads open 3h ago
The theme system: which hooks to call, and the spacing, radius and typography scales. Token names rather than hex values are what let a retheme propagate.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines
list_components reads unknown never probed
Lists the shipped @opointo/ui components: slug, purpose, category, and which render the real iOS system control versus our own component. Cheap, and a good first call. Optional filters: category and tech.

mcp-tool
{ "type": "object", "properties": { "tech": { "enum": [ "system", "glass", "blur" ], "type": "string" }, "category": { "enum": [ "controls", "chrome", "surfaces" ], "type": "string" } } }
arguments 21 lines
get_component reads unknown never probed
Everything needed to write a correct call site for one component: props with types, defaults and value domains, platform applicability, dependencies, and the runtime rules that apply to it. The rules matter as much as the props: correct props that break a rule still render a blank screen.

mcp-tool
{ "type": "object", "required": [ "slug" ], "properties": { "slug": { "type": "string", "description": "e.g. \"button\"" } } }
arguments 12 lines
find_component reads unknown never probed
Takes a UI need in plain language and returns ranked components, including an explicit answer when this catalog deliberately does not ship something and the OS's own control is the right choice. Useful before building a UI control by hand.

mcp-tool
{ "type": "object", "required": [ "need" ], "properties": { "need": { "type": "string", "description": "e.g. \"a progress bar for an upload\"" } } }
arguments 12 lines
check_snippet reads unknown never probed
Takes TSX that uses these components and returns the glass-safety problems in it: animated opacity, the flex:1 collapse, the clipped lens, the conditional mount. Read-only, it never touches the repo. A heuristic text scan, not a structural guarantee.

mcp-tool
{ "type": "object", "required": [ "code" ], "properties": { "code": { "type": "string", "description": "the TSX snippet to check" } } }
arguments 12 lines
emit_app changes data unknown never probed
PAID. Turns an opointo canvas into a working Expo app: navigation, providers, tab bar, screens and the components they need. Returns a recipe to apply to the current project: the exact files with target paths, the dependency install line, and ordered steps. Files marked `skeleton` or `component` are hand-written and device-verified, and verify_app reports any that were changed. Needs the share code from the App Builder's "Send app to agent" button.

mcp-tool
{ "type": "object", "required": [ "appId" ], "properties": { "appId": { "type": "string", "description": "the share code, e.g. \"34ca4babb2\"" }, "override": { "type": "boolean", "description": "emit even when screens are flagged as not ready. Ask the customer first; the flags exist for a reason." } } }
arguments 16 lines

add_screen changes data unknown never probed

PAID. Adds one new screen to an app that was already exported: the screen file, the route that mounts it, the exact line to register it, and how to navigate to it. Reads the .opointo/files.json manifest to work out the route tree and never reads or rewrites existing source, so the one edit to an existing file comes back as a line to add rather than a file to overwrite.

arguments 25 lines

update_components changes data unknown never probed

PAID. Reports what has changed in the opointo-supplied files since export and returns only what moved. Reads the .opointo/files.json the export wrote into the project, so no share code is needed and it works months later. Never touches the customer's own screens, and flags the rare change that needs a code edit rather than a re-copy. This is how the components and app shell we supplied stay current as iOS and Android move.

verify_app reads unknown never probed

PAID. Checks that an emitted app was applied correctly, before it is built. Takes what was written (file paths with byte sizes, package.json dependencies, project config, build toolchain) and returns what is missing, which copy-verbatim files were altered, which packages are absent, whether the config merge expo-router needs was done, and whether the installed Xcode can build this project at all. Catches the ways a long recipe goes wrong, each of which fails silently or points somewhere else.

get_step reads unknown never probed
FREE. Expands one step of an emit_app recipe: the full instruction, why it matters, how to know it worked, and what to do when it did not. emit_app returns steps in short form to stay inside the response budget, so this carries the detail for any step that needs it. Needs the same share code and the step's id.

{ "type": "object", "required": [ "appId", "stepId" ], "properties": { "appId": { "type": "string", "description": "the share code you passed to emit_app" }, "stepId": { "type": "string", "description": "the step id, e.g. \"configure\" or \"write\"" } } }
arguments 17 lines
emit_screen changes data unknown never probed
PAID. Turns one composed screen into a TSX file for an app that already exists, with its own navigator and routes. Returns the complete file inline, the components to install first, and how to mount it. For a whole app with navigation and a tab bar, emit_app is the matching tool. Needs the share code from the App Builder.

mcp-tool
{ "type": "object", "required": [ "compositionId" ], "properties": { "componentName": { "type": "string", "description": "React component name for the file, e.g. \"CheckoutScreen\". Defaults to GeneratedScreen." }, "compositionId": { "type": "string", "description": "the share code, e.g. \"34ca4babb2\"" } } }
arguments 16 lines
install_component changes data unknown never probed
PAID. Adds one component to an existing project. Returns the transitive registry closure in dependency-first install order, the single `expo install` line for the whole closure, every file with its exact target path, the provider nesting it needs, and its runtime rules. It replaces fetching /r/*.json by hand: a component is a closure, not a file, and the ways to get that wrong all fail silently. Foundation components need no licence key.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/b86cd59dccb46c12/badge.svg)](https://brick.blue/agent/b86cd59dccb46c12)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
