mirrorneuron-api 1.1.0

MirrorNeuron REST API

MirrorNeuron API

HTTP gateway for the MirrorNeuron runtime.

The API is a FastAPI/Uvicorn service that exposes runtime operations over REST and forwards them to the MirrorNeuron core through the Python SDK gRPC client.

Features

• Health and runtime summary endpoints.
• Job submission from JSON manifests or uploaded bundle ZIP files.
• Job listing, status, event, graph, metrics, and dead-letter endpoints.
• Job lifecycle controls for cancel, pause, resume, and cleanup.
• Optional bearer-token protection for production mode.
• Request-size and CORS configuration through environment variables.

Tech Stack

Area	Tooling
Runtime	Python 3.9+
Web framework	FastAPI
Server	Uvicorn
Core client	mirrorneuron-python-sdk
Packaging	setuptools with setuptools-scm

Prerequisites

• Python 3.9 or newer.
• A running MirrorNeuron core reachable over gRPC.
• Redis and any runtime dependencies required by the core deployment.

Installation

The released-package installer installs this package automatically and exposes mn-api on your PATH.

Standalone install:

pip install mirrorneuron-api

Developer install:

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[test]"

Configuration

All runtime configuration uses environment variables.

Variable	Default	Description
MN_ENV	dev	Runtime mode. Use prod for protected deployments.
MN_API_HOST	localhost	Bind host for the HTTP server.
MN_API_PORT	4001	Bind port for the HTTP server.
MN_API_TOKEN	unset	Required when MN_ENV=prod.
MN_CORE_HOST	localhost	Core host used to build the default gRPC target.
MN_GRPC_TARGET	unset	Full core gRPC target. Takes precedence over MN_CORE_GRPC_TARGET.
MN_CORE_GRPC_TARGET	unset	Fallback full core gRPC target.
MN_GRPC_TIMEOUT_SECONDS	10	SDK call timeout. Use 0 or none to disable.
MN_API_REQUEST_SIZE_LIMIT_BYTES	5242880	Maximum request body size.
MN_API_CORS_ALLOW_ORIGINS	unset	Comma-separated CORS allowlist.
MN_API_LOG_PATH	~/.mn/logs/api.log	API log file path.
MN_LOG_LEVEL	package default	Log level used by shared logging setup.
MN_LOG_MAX_BYTES	package default	Rotating log size limit.
MN_LOG_BACKUP_COUNT	package default	Rotating log backup count.

Protected endpoints require:

Authorization: Bearer <MN_API_TOKEN>

Running

mn-api

The service listens on http://localhost:4001 by default.

Example production-style local run:

MN_ENV=prod \
MN_API_TOKEN=replace-me \
MN_GRPC_TARGET=localhost:50051 \
mn-api

API Endpoints

Base path: /api/v1

Method	Route	Description
GET	/health	Service health check.
GET	/system/summary	Runtime hardware and pool summary.
GET	/metrics	Runtime metrics summary.
POST	/jobs	Submit a workflow from a JSON manifest.
POST	/bundles/upload	Upload and submit a bundle ZIP.
GET	/jobs	List jobs.
DELETE	/jobs	Clear jobs.
GET	/jobs/{job_id}	Fetch job status.
GET	/jobs/{job_id}/graph	Fetch agent graph details.
GET	/jobs/{job_id}/events	Fetch job events.
GET	/jobs/{job_id}/dead-letters	Inspect dead-letter events.
POST	/jobs/{job_id}/dead-letters/{index}/replay	Replay a dead-letter event.
POST	/jobs/{job_id}/cancel	Cancel a job.
POST	/jobs/{job_id}/pause	Pause a job.
POST	/jobs/{job_id}/resume	Resume a job.

Example health check:

curl http://localhost:4001/api/v1/health

Example authenticated request:

curl \
  -H "Authorization: Bearer $MN_API_TOKEN" \
  http://localhost:4001/api/v1/system/summary

Testing

python3 -m pytest -q

Deployment

The recommended path is the released-package installer in mn-deploy, which installs the API from PyPI alongside the CLI, SDK, Web UI, and core OTP release.

For custom deployments:

1. Install mirrorneuron-api.
2. Start the MirrorNeuron core.
3. Set MN_GRPC_TARGET.
4. Set MN_ENV=prod and MN_API_TOKEN when exposing the API outside a trusted local environment.
5. Run mn-api behind your process manager or service supervisor.

Troubleshooting

Symptom	Check
MN_API_TOKEN error on startup	MN_ENV=prod requires MN_API_TOKEN.
API starts but runtime calls fail	Confirm the core is running and MN_GRPC_TARGET points to it.
Browser requests are blocked	Set MN_API_CORS_ALLOW_ORIGINS for the Web UI origin.
Bundle uploads fail	Check MN_API_REQUEST_SIZE_LIMIT_BYTES and bundle ZIP contents.

Contributing

Keep API changes aligned with the Python SDK and CLI command surface. Add tests for new routes, request validation, and error handling.
