AxioDB is an embedded NoSQL database for Node.js with MongoDB-style queries. It is a pure JavaScript alternative to SQLite with zero native dependencies, no node-gyp compilation, and no platform-specific binaries. Install with 'npm install axiodb' and you have a database — no mongod process, no server setup. Perfect for Electron apps, CLI tools, and local-first applications.

Is AxioDB a replacement for MongoDB?

No. AxioDB is embedded — it runs inside your app with no server. MongoDB is a client-server database for multi-user production systems. Use AxioDB for desktop apps, CLI tools, and local-first applications with 10K–500K documents. Use MongoDB when you need a shared, networked, multi-user database.

Does AxioDB work with Electron?

Yes — Electron is the primary use case AxioDB was built for. Zero native dependencies means no electron-rebuild, no platform-specific .node files, no node-gyp compilation. Just npm install axiodb and it works on Windows, Mac, and Linux without any rebuild step.

What is the difference between AxioDB and better-sqlite3?

better-sqlite3 uses C native bindings and requires compilation via node-gyp. AxioDB is pure JavaScript — it installs in any Node.js environment without compilation or platform-specific builds. AxioDB also uses NoSQL/JSON document queries instead of SQL strings, includes built-in caching and Worker Threads, and works out of the box in Electron without electron-rebuild.

What is the difference between AxioDB and lowdb?

lowdb stores everything in a single JSON file and becomes slow above 1,000–5,000 records due to full-file reads on every operation. AxioDB uses file-per-document tree storage with InMemoryCache, Worker Threads, and auto-indexing — optimized for 10,000–500,000 documents with O(1) lookups by ID and fast filtered queries.

What is the difference between AxioDB and nedb?

NeDB is abandoned (no active maintenance since 2016) and keeps the entire database in memory. AxioDB is actively maintained, uses file-based storage, supports TypeScript, ACID transactions with savepoints and WAL, Worker Threads, AES-256 encryption, custom field indexing, and AxioDBCloud remote access.

How many documents can AxioDB handle?

AxioDB is optimized for 10,000–500,000 documents per collection. For 1M+ documents, migrate to PostgreSQL or MongoDB. AxioDB's InMemoryCache and Worker Threads keep performance fast within this range — documentId lookups take ~1ms and indexed queries take ~2ms on 10,000 documents.

Does AxioDB support TypeScript?

Yes. Full TypeScript type definitions are included out of the box with the axiodb npm package. No @types/axiodb needed.

Does AxioDB work in the browser?

No. AxioDB requires Node.js (v20+) and uses the filesystem for storage. It is a server-side and desktop embedded database. It does not run in browsers.

AxioDBCloud is a TCP-based remote access layer for AxioDB. Deploy AxioDB in Docker or Cloud, then connect from multiple clients using the exact same API as embedded AxioDB — zero code changes. Supports 1,000+ concurrent connections, auto-reconnect with exponential backoff, and heartbeat monitoring.

AI AGENT INTEGRATION

MCP Server

Spin up AxioDB in a container and let Claude (or any MCP-compatible AI agent) talk to it directly — create databases, query documents, run aggregations, manage users and roles, all through 32 tools that log in and enforce the exact same RBAC as the web GUI. It runs in the same process as your existing Docker deployment — no separate install, no new database instance.

Quick Start

The MCP server is opt-in and disabled by default — set AXIODB_MCP=true on the same container you already run for the GUI/TCP server:

bash

1docker run -d \
2  --name axiodb-server \
3  -e AXIODB_GUI=true \
4  -e AXIODB_MCP=true \
5  -p 27018:27018 \
6  -p 27019:27019 \
7  -p 27020:27020 \
8  -v axiodb-data:/app \
9  theankansaha/axiodb

AXIODB_MCP=true only has something to serve once RBAC is actually seeded — that requires AXIODB_GUI=true (the default) or AXIODB_TCP=true + AXIODB_TCP_AUTH=true. See Docker Deployment for every environment variable.

Real Login, Real RBAC — Not a Docker Env Var

Every tool except axiodb_login requires a sessionId. Call axiodb_login first with the seeded default account (admin/admin, same as the GUI) or any other RBAC user, and every subsequent call is checked against that logged-in user's actual role — a View-role session gets a real 403 on write tools, exactly like the GUI would. Nothing is gated by a static container environment variable.

json

1// axiodb_login({ username: "admin", password: "admin" })
2{
3  "statusCode": 200,
4  "message": "Login successful",
5  "data": {
6    "sessionId": "a1b2c3...",
7    "username": "admin",
8    "role": "Super Admin",
9    "permissions": ["db:view", "db:create", "..."],
10    "mustChangePassword": true
11  }
12}

Sessions live in server memory only, 24h sliding TTL — call axiodb_logout when done rather than waiting it out
axiodb_whoami returns the identity/role/permissions behind a given session
axiodb_change_own_password rotates the session and returns a new sessionId
Same login rate limiter as the GUI/TCP login (5 failed attempts / 15 min lockout)

32 Tools, Mirroring the HTTP Control Server 1:1

Every MCP tool maps to the exact same controller and permission check as its HTTP route counterpart — nothing was reimplemented, so behavior (validation, error messages, RBAC) never drifts between the GUI and the MCP surface.

Session

No permission required — login is the gate itself

axiodb_login
axiodb_logout
axiodb_whoami
axiodb_change_own_password

Database

axiodb_create_index
axiodb_drop_index

User Management

user:view / create / update-role / reset-password / delete — Super Admin role only

axiodb_list_users
axiodb_create_user
axiodb_update_user_role
axiodb_reset_user_password
axiodb_delete_user

Role Management

role:view / role:create / role:delete — Super Admin role only

axiodb_list_roles

Out of scope by design: transactions and database export/import are not exposed as MCP tools — kept out of this surface entirely rather than deferred.

Example: Insert & Query From an Agent

text

11. axiodb_login({ username: "admin", password: "admin" })
2   -> sessionId: "a1b2c3..."
3
42. axiodb_create_database({ sessionId, name: "shop" })
5
63. axiodb_create_collection({ sessionId, dbName: "shop", collectionName: "orders" })
7
84. axiodb_insert_document({
9     sessionId, dbName: "shop", collectionName: "orders",
10     document: { customer: "Alice", total: 49.99, status: "paid" }
11   })
12
135. axiodb_query_documents({
14     sessionId, dbName: "shop", collectionName: "orders",
15     query: { status: "paid" }
16   })

Security Notes

Every write/read tool is permission-checked against the caller's actual role on every call, not just at login
An invalid, expired, or missing sessionId is rejected before it ever reaches a database operation
Collection metadata responses (axiodb_get_collection_info) never include the raw AES encryption key — only whether a collection is encrypted
Expose port 27020 only to trusted networks/agents, same guidance as the TCP port — the MCP server carries the same authority as the GUI, just a different transport

Give Your Agent a Database

Deploy the container, enable AXIODB_MCP, and register it with your MCP client.
