WebMCP

WebMCP lets an AI agent that runs inside the browser use the Voice Logica web app the way a person would: find a call, open an agent, walk through a setup guide. The app tells the browser which actions it offers, so the agent calls them directly instead of guessing at buttons.

It is the browser side of Claude and ChatGPT. The table shows the difference.

	WebMCP	MCP server (Claude, ChatGPT)
Where it runs	In your browser tab on app.voicelogica.ai	Claude or ChatGPT calls https://api.voicelogica.ai/api/v1/mcp
Who it acts as	Whoever is signed in to that tab	The account you sign in with when you connect
What it can do	Read and navigate. It never saves, sends or deletes anything	Read and change: agents, calls, campaigns, telephony, the website widget and more
What you set up	Nothing	Add the connector once

What it needs

• A browser or browser agent that supports WebMCP (navigator.modelContext). Without one, the app works as normal and offers no tools.
• For your own data: be signed in to app.voicelogica.ai in that tab. The tools see exactly what your role sees.

The app registers its tools once, when the page loads. An agent that adds WebMCP support to a tab after the page loaded sees no tools: reload the page.

Without signing in

These work on any visit, so an agent can answer product questions and start a sign-up:

• ask_voicelogica: answers a question about the product from the product guide.
• site_info, get_docs_index: what Voice Logica is and where the docs are.
• list_supported_integrations: the CRMs, ERPs, calendars, shops and other systems we connect to.
• get_product_map on app.voicelogica.ai/for-agents: the whole product on one page.
• get_sign_in_options, get_sign_up_requirements, start_sign_up, get_password_reset_steps on the sign-in, sign-up and password pages. start_sign_up opens the form with the email filled in. It never types a password.

Signed in

• Find and open: search_calls / open_call, search_contacts / open_contact, list_agents / open_agent, list_campaigns / open_campaign, list_workflows / open_workflow, list_tasks / open_task, list_mailboxes, search_email_threads / open_email_thread, search_users.
• Move around: list_app_pages, open_page, get_current_page, get_session.
• Setup guides: list_setup_guides, get_setup_guide, start_setup_guide, open_guide_step. There are guides for a phone line or SIP trunk, an office PBX, going live, editing an agent, workflows, transfers, appointments, knowledge, campaigns, the team, SMS, the website widget and more. Each step opens the right page, and says which Claude tool does the same step from a chat.

Calls, contacts and emails contain text that other people wrote. The app marks those answers as untrusted, and a well-behaved agent treats them as data, never as instructions.

For agents and crawlers

• app.voicelogica.ai/for-agents: the public entry page for AI agents.
• app.voicelogica.ai/llms.txt and llms-full.txt: the product guide as plain text.

Can a browser agent change my agent or start calls through WebMCP?

No. WebMCP in Voice Logica only reads and navigates. To change settings, start calls or turn on the website widget from a chat, connect Claude or ChatGPT.

My browser agent sees no tools

Reload app.voicelogica.ai after the agent is active in the tab. If it still sees none, the browser does not support WebMCP yet.
