For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/variant-os-app-mcp-d87f961d56
GET https://www.mcpbundles.com/api/directory/v1/servers/variant-os-app-mcp-d87f961d56?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/variant-os-app-mcp-d87f961d56/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/variant-os-app-mcp-d87f961d56/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

open_bridge_test
Opens one isolated Variant OS bridge run and returns the continuation required to keep polling it until terminal.
Open bridge test — Opens one isolated Variant OS bridge run and returns the continuation required to keep polling it until terminal.
Record bridge widget event — Records one app-authored bridge receipt. This tool is callable by the widget only.
Acknowledge legacy bridge handoff — Compatibility receipt for older Bridge Lab clients. Current runs record this receipt automatically inside await_bridge_test_event.
Acknowledge legacy batch manifest — Compatibility receipt for older Bridge Lab clients. Current runs record this receipt automatically inside await_bridge_test_event.
Claim bridge target — Claims one batch target for one Work subagent and returns only its design-system and vehicle-identity references.
Report bridge target step — Records target-scoped reference verification and image generation under an active worker claim.
Get bridge test status — Returns the authoritative run state, receipt counts, failure evidence, and required next action.
Get bridge batch status — Returns target worker states so the coordinator can fill open worker slots and finalize the batch.
Await bridge test event — Waits for the component's exact Bridge Lab handoff and records its model receipt inside the same call. A timeout is nonterminal and must be polled again.
Report bridge test step — Records model-side pixel verification, generation receipts, or an exhausted terminal blocker. Image submission records its own authoritative start receipt.
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.
Variant Os App is an MCP server at variant-os-app.link. MCPBundles discovered 25 tools on the live endpoint.
How do I connect Variant Os App to my AI agent?
Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.

Operate Variant Os App?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
— Submits one unique ChatGPT conversation image to its exact target_id with three idempotent download attempts.
Finalize bridge test — Completes a bridge run only after all references and unique target submissions have durable receipts.
Finalize bridge batch — Completes a Work-subagent batch only after every target has one unique submitted image receipt.
Open production generation run — Opens one durable Variant OS production run and mounts the verified reference handoff widget.
Record production widget event — Records one app-authored production handoff receipt. Callable by the widget only.
Acknowledge legacy production target manifest — Compatibility receipt for older production clients. Current runs record this receipt automatically inside await_generation_run_event.
Claim production target — Claims one identity-specific target for one Work subagent and returns only that target's design and vehicle identity references. Color batches do not use this tool.
Report production target step — Records target-scoped pixel verification, generation start/completion, or a recoverable target failure.
Get production generation status — Returns durable production target, receipt, candidate, and blocker state.
Await production generation event — Waits for the component's exact handoff manifest and records its model receipt inside the same call. Keep polling in the same kickoff turn while next_action is POLL_FOR_COMPONENT_HANDOFF.
Submit production candidate — Stages one generated conversation image into its exact Work task as an unapproved Review candidate.
Report exact-year candidate audit — Records the evidence-based exact-year, required-text, and cross-output distinctness audit for one submitted VA Parent Builder design candidate.
Finalize production generation run — Completes a production run only after every target has a unique generated image and staged Review candidate receipt.
Save generated designs to open Parent Builder job — After every requested standalone image has been generated in ChatGPT, saves each expected Design slot in that exact Variant OS job. For a new parent, provide all three. For a focused redo, call the tool again with the same job code and only the Design field the VA is replacing.
Save generated images to open Work job — Saves one generated image to an open Variant OS Work job without replacing completed outputs. Use output_number when supplied; if it is omitted, Variant OS uses the next unsaved output in order. This is a finite post-generation action: continue only through the missing outputs in the user's copied save message, never retry an error, never exceed that message's call count, and stop immediately on COMPLETE or the first error.
MCPBundles probed 25 tools on the live server. The tool list on this page reflects what was discovered at the last refresh — connect your client to see the full set available to your session.
What authentication does Variant Os App require?
No provider sign-in was required during MCPBundles' probe. Your client may still need MCPBundles credentials depending on how you connect.
