How much does Asteroid cost?

Freemium per directory listings with flexible plans and custom built agent options; specific rates not captured in retrieved materials.

Does Asteroid support MCP and tool calling?

Full under the Agentic Index verification standard. Asteroid publishes public evidence of Model Context Protocol (MCP) support, tool calling, and API or SDK extensibility for connecting agents to external tools. Evidence basis: Developer documentation covers API and MCP triggering with structured results, agents deploy as API endpoints, and developers embed browser automation within their own products, Asteroid materials 2026-07-22. Graded from public evidence only against the Agentic Index 14 point capability taxonomy. No vendor pays for placement.

Does Asteroid give you tracing and observability into agent runs?

Full under the Agentic Index verification standard. Asteroid publishes public evidence of tracing, observability and audit logging into agent runs, so a team can see what an agent did and why. Evidence basis: The graph of nodes architecture is designed for observability, with live supervision, real time failure detection, and full visibility into agent runs, Asteroid materials 2026-07-22. Graded from public evidence only against the Agentic Index 14 point capability taxonomy. No vendor pays for placement.

Supervised browser and computer use agents for regulated back offices: a frontier model drives the portal, then the agent compiles its own deterministic script and can even discover the private API underneath. Graph based, self healing, HIPAA ready, with live human supervision. YC W25.

Asteroid builds supervised AI browser and computer use agents for regulated back office work, with a three mode execution ladder: a frontier model first drives the browser the way a person would (read the screen, reason, act, any portal, zero setup); from those runs the agent writes its own deterministic script that replays instantly without the model at a fraction of the cost, with AI handling only judgment calls and keeping the script tuned as the portal evolves; and Astro, the agent builder, can watch how a portal talks to its own servers, find the private API underneath, and call it directly. Agents run as graphs of focused nodes for reliability, observability, and safe tool access, across browser, Linux, and Windows environments.

Gen 2 agents get their own computer, write code, self heal, and learn over time (one workflow went from six minutes to 67 seconds). Live Supervision lets operators monitor, intervene, and guide agents in real time, with built in safeguards and failure detection; agents operate under customer credentials with full visibility and are described as HIPAA ready. Production use cases include insurance quoting across carrier portals, patient data entry and prior authorization in healthcare, vendor verification on government sites, and mortgage data entry across lender portals. YC W25.

Integrations

Agents connect to existing stacks via APIs, Slack, email, and Google Sheets; runs trigger from the UI, the API, or MCP with structured results back; agents deploy as API endpoints (e.g. the scheduling endpoint of an EHR) and pair with voice agents to push captured data into legacy CRMs and EHRs through the UI.
