OmniBioAI Tool Execution Service (TES): secure, validated execution of bioinformatics tools on local/HPC/remote backends

OmniBioAI Tool Execution Service (TES)

omnibioai-tool-exec is a standalone Tool Execution Service (TES) that enables secure, validated, and reproducible execution of bioinformatics tools across heterogeneous compute environments (local, HPC, cloud, or remote servers).

It is designed to be used by agentic AI systems (such as OmniBioAI) where an LLM interprets user intent, but never executes tools directly. Instead, all execution is delegated to TES via a strict API contract.

---

Why TES exists

LLMs are good at understanding intent, but bad at safely running tools.

TES solves this by acting as a control plane between AI agents and real compute:

• Validates tool inputs and resource requests
• Matches tools to compatible execution environments
• Executes tools in a controlled adapter layer
• Tracks run lifecycle (submitted → running → completed/failed)
• Returns structured, machine-readable results

This prevents:

• Arbitrary command execution
• Hallucinated tool outputs
• Tight coupling between UI, AI, and infrastructure

---

Core Concepts

Tool

A tool is a declarative definition of:

• Inputs schema (JSON Schema)
• Outputs schema
• Requirements (e.g. BLAST database, reference genome)

Example:

tool_id: blastn
inputs_schema:
  required: [sequence, database]

Server

A server represents an execution environment:

• Local machine
• HPC cluster
• Kubernetes
• Remote API-backed service

Each server advertises:

• Which tools it supports
• Available resources
• Storage constraints
• Runtime policies

Adapter

An adapter translates a validated run request into a real execution:

• Local process
• Container
• Job scheduler
• HTTP call

Adapters are pluggable and isolated from the API layer.

Key rule: LLMs never execute tools. TES does.

---

API Overview

TES exposes a REST API (OpenAPI / FastAPI-based).

Discovery

• GET /api/tools – list available tools
• GET /api/servers – list available servers and capabilities

Execution

• POST /api/runs/validate – validate tool + inputs + resources
• POST /api/runs/submit – submit a run
• GET /api/runs/{run_id} – get run status
• GET /api/runs/{run_id}/results – fetch results when ready

---

Example: BLAST run lifecycle

1. Validate

POST /api/runs/validate
{
  "tool_id": "blastn",
  "inputs": {
    "sequence": ">q\nACGTACGT",
    "database": "ecoli_demo"
  },
  "resources": { "cpu": 2, "ram_gb": 2 }
}

2. Submit

POST /api/runs/submit
→ { "run_id": "run_abc123" }

3. Poll

GET /api/runs/run_abc123
→ state: RUNNING | COMPLETED | FAILED

4. Fetch results

GET /api/runs/run_abc123/results
→ structured JSON results

---

Demo Adapter (Current)

The default configuration includes a local demo adapter that returns mock BLAST results.

This is intentional:

• It validates the entire execution pipeline
• It allows frontend and agent development without heavy dependencies
• It can be replaced with a real backend without changing the API

Different inputs currently return the same demo output. Replace the adapter to enable real BLAST execution.

Running the Service

Requirements

• Python ≥ 3.11
• pip or pipx

Install (editable)

pip install -e .

Run

Configuration

Tools

Defined via YAML:

- tool_id: blastn
  display_name: BLASTN
  inputs_schema:
    required: [sequence, database]

Servers

Defined via YAML:

- server_id: local_demo
  adapter_type: local
  capabilities:
    tools:
      - tool_id: blastn
        features:
          databases: [ecoli_demo]

Integration with OmniBioAI

TES is designed to be used server-to-server.

Typical flow:

1. User chats with OmniBioAI
2. LLM identifies a tool intent (blast:)
3. Django backend calls TES
4. TES executes and returns results
5. Results are rendered in chat UI

No browser-to-TES calls are required.

---

What TES is not

• ❌ A workflow engine (Nextflow/WDL belong elsewhere)
• ❌ A UI
• ❌ An LLM executor
• ❌ A database

TES is a secure execution boundary.

---

Roadmap

• Real BLAST+ adapters (local / container / HPC)
• OMIM / annotation tools
• Async callbacks & long-running job tracking
• Auth / multi-tenant policies
• Artifact storage backends (S3, GCS, POSIX)
