Ar MCP

@muovi/mcp-server

Model Context Protocol (MCP) server for [Muovi](https://muovi.com.ar) — LATAM's trust-first local services marketplace.

This package lets MCP-aware clients (Claude Desktop, Cursor, Claude Code, and any other MCP host) discover Muovi's verified LATAM service professionals, browse the service catalog and city list, read reviews, deep-link a user into the on-platform task-creation flow, and save a task draft the user publishes themselves. It is a thin wrapper over Muovi's public /v1 REST API.

Stdio mode. The package ships an npx-runnable binary that speaks JSON-RPC over stdin/stdout. The hosted HTTP/SSE variant is tracked separately (Muovi MOB-142).

What it exposes

Every tool is read-only except muovi_create_task_draft, which saves a draft on Muovi:

Anti-leakage policy

Muovi is on-platform-only. Phone, email, and WhatsApp handles are never returned by the public API — contact between consumers and professionals happens exclusively through Muovi's in-app conversation flow, reachable from each pro's profile_url.

This server enforces the policy twice:

1. The /v1 API strips contact data server-side.
2. Every tool response in this package also runs through a local anti-leakage detector (a Node-compatible mirror of src/lib/anti-leakage/detector.ts in the Muovi web repo). If a leak is detected at the agent boundary the tool returns a stable error to the LLM client and refuses to surface the payload.

Hosts that integrate this server must not synthesise off-platform contact handles from any field. Driving the user to profile_url (optionally with the deep-link query string) is the only sanctioned contact channel.

Installation & configuration

Claude Desktop

Open ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows) and add the server under mcpServers:

{

"mcpServers": { "muovi": { "command": "npx", "args": ["-y", "@muovi/mcp-server"] } } }

If you have a Muovi API key (see Authentication below), pass it via env:

{

"mcpServers": { "muovi": { "command": "npx", "args": ["-y", "@muovi/mcp-server"], "env": { "MUOVI_API_KEY": "your-key-here" } } } }

Restart Claude Desktop after editing the config.

Cursor

Add to ~/.cursor/mcp.json (or your workspace's .cursor/mcp.json):

{

"mcpServers": { "muovi": { "command": "npx", "args": ["-y", "@muovi/mcp-server"] } } }

Claude Code

Register the server with the Claude Code CLI:

claude mcp add muovi --command "npx" --args "-y" "@muovi/mcp-server"

Or add it manually to your Claude Code settings:

{

"mcpServers": { "muovi": { "command": "npx", "args": ["-y", "@muovi/mcp-server"] } } }

Manual / scripting

npx -y @muovi/mcp-server

The process reads JSON-RPC on stdin and replies on stdout. All log output goes to stderr.

Authentication (optional)

All /v1 endpoints are public and unauthenticated by default. If your client has been issued a Muovi API key (higher rate-limit tier), set MUOVI_API_KEY in the server's environment and the package will forward it as the X-API-Key header on every request.

You can also override the API base URL for testing:

MUOVI_API_BASE_URL=https://staging.muovi.com.ar/api/v1 npx -y @muovi/mcp-server

muovi_create_task_link builds its link on MUOVI_WEB_BASE_URL when that is an https origin with no path, and on https://muovi.com.ar otherwise.

Example agent workflow

A typical Claude conversation that uses these tools:

1. User asks for "an electrician in Palermo who's properly licensed".
2. Agent calls muovi_list_services to map "electrician" → electricidad.
3. Agent calls muovi_list_cities to confirm palermo is a valid neighborhood under caba.
4. Agent calls muovi_search_professionals with { service: "electricidad", neighborhood: "palermo", has_matricula: true } and gets up to 5 professionals. Without both a service and a barrio the tool answers an error asking for them, so the agent asks the user first.
5. Agent shows the results and offers two choices: a task for one of those professionals, or a general request to get offers from several.
6. For one professional, the agent can call muovi_get_professional and muovi_get_reviews with that result's id.
7. Agent calls muovi_create_task_link with { professional_id, service_slug: "electricidad" } and surfaces the resulting URL — or calls muovi_create_task_draft with { service_slug: "electricidad", professional_id, description } so the user lands on a draft already written. For a general request it calls muovi_create_task_draft without a professional.
8. User follows the link, lands on Muovi, reviews the draft, signs in, and publishes the task in the on-platform flow.

Step 8 — the on-platform flow — is where the task is published, and where payments and disputes run.

Local development

This package is the standalone muovi-latam/mcp-server repo. Clone it, install, and run tests:

git clone git@github.com:muovi-latam/mcp-server.git

cd mcp-server npm install npm test # unit + integration + OpenAPI drift checks npm run typecheck # strict TypeScript npm run build # emits dist/

The OpenAPI drift test parses public/openapi.yaml and asserts each tool's input schema matches the corresponding operation's parameters exactly — adding a query param to /v1 requires updating the corresponding tool (and vice versa).

Publishing

npm publish is intentionally not wired into CI. Releases are cut manually from a clean tag:

npm version patch    # or minor / major

npm publish --access public git push --follow-tags

prepublishOnly runs clean + build + test before any publish.

MCP Registry (mcp-publisher)

Beyond npm, this server is listed in the Model Context Protocol registry via the committed server.json manifest. Publishing to the registry is a manual step — there is deliberately no CI auto-publish (the registry is a low-frequency, human-gated surface, and namespace auth is interactive).

Committed namespace: ar.com.muovi/mcp-server — the reverse-DNS form of muovi.com.ar. This value lives in both server.json (name) and package.json (mcpName) and the two must stay byte-identical (the server-json test enforces equality). It must also match the identity you authenticate as with mcp-publisher (see below).

One-time namespace ownership setup

Prove ownership of the ar.com.muovi namespace once, before the first publish:

• DNS (preferred): add the TXT record that mcp-publisher login dns prints to the muovi.com.ar zone, then authenticate against that domain. This ties the namespace to the domain we already control.
• GitHub OAuth (fallback): mcp-publisher login github — authenticates via the muovi-latam GitHub org. Only use this if DNS verification is unavailable; the authenticated identity still has to line up with the committed ar.com.muovi/mcp-server namespace.

If the committed namespace and the authenticated identity disagree, mcp-publisher publish will reject the manifest — fix the namespace (in both files) or the login, do not force it.

Publish steps

mcp-publisher validate ./server.json   # checks against the live registry schema

mcp-publisher publish # publishes server.json under the authenticated namespace

validate is the step that confirms the manifest matches the current registry schema version — run it every time; the pinned $schema in server.json is a hint, not a guarantee the live schema hasn't moved.

Version-bump discipline

The server-json test asserts that four version fields agree. On every version bump, update all of them together, then re-publish to both npm and the registry:

1. package.json → version
2. src/server.ts → PACKAGE_VERSION
3. server.json → version
4. server.json → packages[0].version

Honest gating notes

The manifest advertises capabilities that are not yet fully live. Keep these caveats in mind (and do not overstate them to users):

• Remote transport (remotes[].url = https://mcp.muovi.com.ar/) is only truthful once that endpoint reliably answers JSON-RPC initialize over streamable-HTTP. That hosted surface is tracked in MOB-207; until it lands, the stdio package (npx @muovi/mcp-server) is the only transport that actually works.
• `muovi_create_task_draft` answers "not available" while task handovers are switched off on the server (TASK_HANDOVERS_ENABLED), which is the default.
• `muovi_get_professional` and `muovi_get_reviews` rema
