Security runtimes for AI agents and MCP systems
Start a bounded runtime against your agent, MCP server, or tool-using workflow. Get reproducible findings, signed evidence, and an audit-ready report.
AI risk moved from prompts to actions.
Modern agents read untrusted context, choose tools, call APIs, use delegated credentials, and act across systems. Existing AppSec tools were built for code, packages, and web endpoints — they do not fully exercise the trust boundaries created when an agent turns instructions into actions.
Tachyonic was built for that surface: agents, MCP servers, tool calls, runtime policy, and evidence that survives review.
From target to signed evidence.
Bounded runtime execution
Every runtime starts with explicit target, region, policy, and budget. Duration, tokens, and spend are capped before the run starts. Network egress is deny-default. Credentialed, destructive, and exploit-class actions can pause for approval.
Attack coverage for agentic systems
Tests prompt injection, tool abuse, MCP trust-boundary failures, permission escalation, sensitive data disclosure, multi-turn manipulation, and implementation flaws. The scanner covers 210 attack patterns; the full library expands to 237.
Signed evidence, not just a PDF
Each runtime emits an artifact bundle: findings, payloads, request and response captures, lifecycle events, logs, runtime policy, and report output — portable across review, remediation, customer assurance, and audit.
CLI, API, and dashboard workflows
Run from the terminal, wire into CI, or manage runtimes from the platform. The same runtime surface supports local testing, hosted runtimes, approval review, artifacts, and reports.
Three commands from target to evidence.
Start
Starts a bounded runtime in the selected region. Policy, budget, and target are explicit. Returns a runtime ID.
Watch
Follows the runtime until it reaches a terminal state. Shows status transitions and exits cleanly for CI or scripted workflows.
Collect
Lists the evidence bundle: findings, report output, request and response captures, logs, and artifact URLs.
The runtime holds the boundary.
Region-pinned execution
Runtimes execute in selected US or EU regions.
Default-deny egress
Network access follows the runtime allowlist.
Approval gates
Credentialed, destructive, and exploit-class actions pause before execution.
Budget enforcement
Runtime duration, tokens, and spend are bounded.
Artifact-backed logs
Runtime logs are captured as evidence artifacts.
Signed evidence
Runtime output is packaged and signed for review and audit trails.
What Tachyonic tests.
AI coding agents
Before they touch repositories, secrets, or build systems.
MCP servers
Before tools, schemas, and transport boundaries reach production.
Browser and support agents
Before untrusted pages, tickets, emails, or documents become instructions.
Voice agents
Before calls, transcripts, and delegated actions reach production systems.
RAG and tool-enabled apps
Before retrieval, function calls, and actions cross trust boundaries.
Internal agentic workflows
Anything that turns natural language into infrastructure action.
Backed by published research.
Tachyonic research has produced confirmed vulnerabilities, a source-code-level MCP SDK audit, GitHub security advisories, and public case studies.
Mapped to frameworks your team already uses.
Evidence packages support SOC 2, ISO 42001, EU AI Act readiness, customer assurance, and internal review. The product does not replace compliance work — it gives teams reproducible security evidence.
