Blumira

Blumira MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with structured access to Blumira SIEM platform data and operations.

Note: This project is maintained by Wyre Technology.

Quick Start

Claude Desktop — download, open, done:

1. Download blumira-mcp.mcpb from the latest release
2. Open the file (double-click or drag into Claude Desktop)
3. Enter your Blumira JWT token when prompted

No terminal, no JSON editing, no Node.js install required.

Claude Code (CLI):

claude mcp add blumira-mcp \
  -e BLUMIRA_JWT_TOKEN=your-jwt-token \
  -- npx -y github:WYRE-AI/blumira-mcp

See Installation for Docker and from-source methods.

Features

Installation

Option 1: MCPB Bundle (Claude Desktop)

The simplest method — no terminal, no JSON editing, no Node.js install required.

1. Download blumira-mcp.mcpb from the latest release
2. Open the file (double-click or drag into Claude Desktop)
3. Enter your Blumira JWT token when prompted

For Claude Code (CLI), one command:

claude mcp add blumira-mcp \
  -e BLUMIRA_JWT_TOKEN=your-jwt-token \
  -- npx -y github:WYRE-AI/blumira-mcp

Option 2: Docker

docker compose up

Compose will not start until CONDUIT_S2S_SECRET is set. See Docker Deployment.

Or pull the pre-built image:

# Generate the secret first: openssl rand -hex 32
docker run -d \
  -e CONDUIT_S2S_SECRET \
  -e BLUMIRA_JWT_TOKEN \
  -e AUTH_MODE=env \
  -p 127.0.0.1:8080:8080 \
  ghcr.io/wyre-ai/blumira-mcp:latest

The image defaults to AUTH_MODE=gateway and binds 0.0.0.0 inside the container. HTTP startup refuses to run unless CONDUIT_S2S_SECRET is a real secret (empty values and known placeholders such as replace-with-a-real-secret exit non-zero). Publish the port on 127.0.0.1 (as above). In gateway mode, send vendor credentials on each /mcp request (X-Blumira-Client-ID + X-Blumira-Client-Secret, or X-Blumira-JWT-Token); the server does not fall back to environment credentials. Set AUTH_MODE=env only for a single-tenant container that should use BLUMIRA_JWT_TOKEN.

Every /mcp request must also send X-Gateway-S2S. The check is verifyS2sHeader in src/s2s-verify.ts: the header value is t=<unix seconds>,v1=<hex>, where the hex is HMAC-SHA256 of the literal string t=<unix seconds> keyed with CONDUIT_S2S_SECRET (64 lowercase hex characters). The timestamp must be within 300 seconds of the server clock. A missing or invalid header is HTTP 401, before vendor credentials are read.

TS=$(date +%s)
SIG=$(printf 't=%s' "$TS" | openssl dgst -sha256 -hmac "$CONDUIT_S2S_SECRET" -hex | awk '{print $NF}')
curl -sS http://127.0.0.1:8080/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H "X-Gateway-S2S: t=${TS},v1=${SIG}" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

With AUTH_MODE=env, that signed request uses BLUMIRA_JWT_TOKEN from the container. With AUTH_MODE=gateway, add X-Blumira-JWT-Token or X-Blumira-Client-ID and X-Blumira-Client-Secret as well.

Standalone local use that cannot sign requests: set MCP_ALLOW_INSECURE_DEV=1 and do not set CONDUIT_S2S_SECRET. Startup logs a warning, skips the S2S check, and binds 127.0.0.1 only. The image sets MCP_HTTP_HOST=0.0.0.0, so this bypass also requires -e MCP_HTTP_HOST=127.0.0.1. Any other bind address refuses to start. Do not publish that port off loopback.

Option 3: From Source

git clone https://github.com/WYRE-AI/blumira-mcp.git
cd blumira-mcp
npm ci
npm run build

Configuration

Variable	Description	Default
BLUMIRA_JWT_TOKEN	JWT token for authentication (stdio and AUTH_MODE=env)	—
MCP_TRANSPORT	Transport mode (stdio or http)	stdio
MCP_HTTP_PORT	HTTP server port	8080
MCP_HTTP_HOST	Interface the HTTP server binds	127.0.0.1
CONDUIT_S2S_SECRET	Required for HTTP. HMAC secret checked against X-Gateway-S2S on /mcp. Generate with openssl rand -hex 32. If empty or a known placeholder, the HTTP server logs an error and exits non-zero. The value is never logged.	—
MCP_ALLOW_INSECURE_DEV	Set to 1 to start HTTP without CONDUIT_S2S_SECRET. Logs a warning, does not enforce S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST refuses to start. Local development only.	unset
AUTH_MODE	env uses process environment credentials (stdio and single-tenant HTTP). gateway requires per-request vendor headers and never falls back to the environment. The Docker image and Compose file default to gateway.	env when unset; gateway in Docker and Compose
LOG_LEVEL	Log level (debug, info, warn, error)	info

/health and /healthz stay unauthenticated and do not read credentials. The stdio transport does not use CONDUIT_S2S_SECRET.

Domains

The server uses decision-tree navigation. Start with blumira_navigate to pick a domain:

Domain	Tools
findings	List findings, get finding, get finding details, resolve finding, assign owners, list/add comments
agents	List devices, get device, list agent keys, get agent key
users	List users
resolutions	List available resolutions
msp	List/get accounts, list/get/resolve findings, assign owners, comments, list devices/keys, list users

Filtering

Blumira supports rich query filtering on list endpoints:

status.eq=10              # Exact match
severity.in=HIGH,CRITICAL # Multiple values
created_at.gt=2026-01-01  # Greater than
name.contains=malware     # Substring match
!status.eq=30             # Negation

Pass filters as tool input parameters — the server handles query string construction.

Docker Deployment

Copy .env.example to .env and fill in your credentials, including CONDUIT_S2S_SECRET. Compose will not start if that variable is missing, and it publishes the HTTP port on 127.0.0.1 only.

cp .env.example .env
# Edit .env with your Blumira JWT token and CONDUIT_S2S_SECRET
docker compose up -d

Development

npm ci
npm run build       # Build the project
npm run dev         # Watch mode
npm run test        # Run tests
