mcp-server-axiomSAFE
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
A JavaScript port of the official Axiom MCP server that enables AI agents to query data using Axiom Processing Language (APL).
This implementation provides the same functionality as the original Go version but packaged as an npm module for easier integration with Node.js environments.
Installation & Usage
MCP Configuration
You can run this MCP server directly using npx. Add the following configuration to your MCP configuration file:
{
"axiom": {
"command": "npx",
"args": ["-y", "mcp-server-axiom"],
"env": {
"AXIOM_TOKEN": "",
"AXIOM_URL": "https://api.axiom.co",
"AXIOM_ORG_ID": ""
}
}
}Local Development & Testing
Installation
npm install -g mcp-server-axiom
Environment Variables
The server can be configured using environment variables:
AXIOM_TOKEN(required): Your Axiom API tokenAXIOM_ORG_ID(required): Your Axiom organization IDAXIOM_URL(optional): Custom Axiom API URL (defaults to https://api.axiom.co)AXIOM_QUERY_RATE(optional): Queries per second limit (default: 1)AXIOM_QUERY_BURST(optional): Query burst capacity (default: 1)AXIOM_DATASETS_RATE(optional): Dataset list operations per second (default: 1)AXIOM_DATASETS_BURST(optional): Dataset list burst capacity (default: 1)PORT(optional): Server port (default: 3000)
Running the Server Locally
- Using environment variables:
export AXIOM_TOKEN=your_token mcp-server-axiom
- Using a config file:
mcp-server-axiom config.json
Example config.json:
{
"token": "your_token",
"url": "https://custom.axiom.co",
"orgId": "your_org_id",
"queryRate": 2,
"queryBurst": 5,
"datasetsRate": 1,fa8bbf7fef9cOBSERVED · 2026-10-12Connect
Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions
What tools does mcp-server-axiom expose?
3 in total: 3 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is mcp-server-axiom safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does mcp-server-axiom need?
It reads AXIOM_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does mcp-server-axiom run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-server-axiom at 1.1.0.
How current is this page?
The grade is for one exact copy of the source (fa8bbf7fef9c), read on 2026-10-12. The repository is watched and re-audited when it changes.
