Hosted MCP services for your AI agents.

Apparatus gives your coding agent the capabilities it lacks: a voice and a way to reach you, a browser, web search, a sandbox, document handling, and more. One login, one bill, credentials managed in Vault.

Waitlist opens with launch. Check back when the page flips to Available.

01 / Problem

The problem

Every team wiring up AI agents rebuilds the same plumbing: a voice channel, a headless browser, web search, a code sandbox, document parsing, each on every machine, each with its own API key pasted into a config. Apparatus hosts those capabilities as MCP services so the agent just calls them, with the keys held in Vault and never in the model context.

02 / The catalog

The services

01

Herald, voice and human-in-the-loop

Your agent speaks a question and waits for your answer instead of stalling in a silent terminal. Notify, approve, and escalate across any device.

02

Prowl, browser automation

A managed headless browser your agent drives in the cloud: navigate, click, extract, screenshot. No local Playwright to babysit.

03

Scry, search and research

Fresh web knowledge: search, fetch a page as clean markdown, or run a cited multi-source research pass.

04

Crucible, sandbox and compute

An isolated environment where the agent runs code and returns the output, without touching your machine.

05

Scribe, documents

Parse PDFs, docx, and images with OCR; convert between formats; render Mermaid and Graphviz to images.

06

Delve, database access

Safe, gated SQL over your own databases: schema and reads open, writes behind an approval gate.

07

Raven, email

Read, search, and draft mail. Sending always passes an approval gate; nothing auto-sends.

08

Chorus, messaging

Two-way Slack, Discord, and Telegram: post, read a channel, and relay replies back to the agent.

09

Mirage, media

Generate and edit images, transcribe audio, and pull frames from video.

10

Anvil, repo and CI

Read a PR, comment, and check or trigger CI on your own repos, with writes gated.

03 / How it works

One platform behind every service

01

One platform, many services

Each capability is its own MCP service at its own endpoint, enabled and billed on its own. Turn on what you need.

02

Credentials stay in Vault

Every service leases its keys per call from Vault, with attribution. Nothing secret is stored here, and nothing ever enters the model context window.

03

Built on the suite

One GhostStack login through Identity, the shared SaaS foundation, and the never-auto-send invariant. Any tool that needs an LLM step calls Cortex.

04

Works with any MCP client

Claude Code, Cursor, or your own agent. Apparatus exposes tools over MCP; it does not run your agent for you.

Coming soon

Apparatus is not available yet. The first services are in build. This page flips to Available, with a signup, when the backend accepts customers.
