Infrastructure MCP Server

Give Claude Code, Cursor, and other AI agents safe access to your real infrastructure — without giving them raw SSH access.

A self-hosted Model Context Protocol server that exposes high-level, auditable tools (disk_usage(), docker_restart(), grafana_alerts(), ...) instead of execute(command). Every call is inventory-driven, structured, and logged — the agent reasons about infrastructure; this server is the only thing that actually touches it.

Status: early, actively developed. See Roadmap for what's implemented and what's coming.

Manage: ✓ Linux   ✓ Docker   ✓ Kubernetes   ✓ Proxmox   ✓ Grafana   ✓ Cisco (MikroTik, UniFi, Prometheus/Loki, Home Assistant, and more are on the Roadmap — not shipped yet.)

Works with: ✓ Claude Code   ✓ Cursor   ✓ OpenAI Codex   ✓ Gemini CLI   ✓ Windsurf   ✓ Hermes (MCP is an open, client-agnostic protocol — any spec-compliant client works; these are just the ones people actually use it with.)

Quick Start

git clone https://github.com/radumalica/infrastructure-mcp.git
cd infrastructure-mcp
go build -o bin/infrastructure-mcp ./cmd/server

cp configs/inventory.example.yaml configs/inventory.yaml   # fill in your own targets

Point your MCP client at the binary — see Connecting an AI Agent for Docker and remote-HTTP setups too:

{
  "mcpServers": {
    "infrastructure": {
      "command": "/path/to/bin/infrastructure-mcp",
      "args": ["-inventory", "/path/to/configs/inventory.yaml"]
    }
  }
}

Example Conversation

You: My archive server feels slow, and I'm seeing errors in Grafana. Can you find out why?

Claude, using Infrastructure MCP:

  1. cpu_usage(server: "archive")                          → 92% used, status: "warning"
  2. docker_ps(server: "archive")                           → prometheus: "Restarting (1) 4 seconds ago"
  3. docker_logs(server: "archive", container: "prometheus") → "panic: too many open files"
  4. grafana_alerts(instance: "main")                        → firing: HighDiskUsage on archive:/

Claude: Root cause found — archive is at 91% disk usage, which is causing Prometheus
to crash-loop on startup ("too many open files" from a corrupted WAL it can't
compact into the remaining space). Free up space on `/` (or expand it), then run:

  docker_restart(server: "archive", container: "prometheus", confirm: true)

Four tool calls, one root cause, zero raw shell access. Every call above is inventory-driven, logged, and returns structured JSON — see Examples for the actual response shapes.

Current Features

Tools implemented and tested against the real MCP protocol so far:

Cross-cutting, since v0.1

• Legacy network device support: Telnet transport, SSH legacy-crypto negotiation, transparent per-target protocol dispatch, SSH public-key auth for routers/switches

• Structured error contract on every tool (message, recommendation, retryable, category)

• Structured per-execution logging (tool, user, target, duration, result, error)

• Host-key verification fail-closed by default, with explicit opt-outs for lab use

• Dual MCP transport: stdio (local subprocess clients) and Streamable HTTP (remote clients), from the same binary — HTTP is fail-closed by default, requiring a bearer token (MCP_HTTP_TOKEN) unless explicitly opted out for lab use

• Docker image (multi-arch, GHCR) + Docker Compose, with a self-check -healthcheck mode for shell-less containers

• CI/CD: PR-gated build/vet/lint/race-tested-CI, automatic semantic versioning + changelog + image publish + Trivy scan on merge to main — see CI/CD

Why

AI agents are increasingly asked to help operate infrastructure — check disk space, restart a container, look at recent errors. The naive way to enable this is to hand the agent raw SSH/shell access. That's fast to build and dangerous to run: no audit trail, no input validation, no blast-radius control, and every agent has to independently learn how to safely operate every kind of system.

Infrastructure MCP Server is the alternative: a single, self-hosted service that exposes meaningful, structured, inventory-driven tools (disk_usage(), docker_restart(), grafana_alerts()) instead of execute(command). Agents reason about infrastructure; this server is the only thing that actually touches it.

Goals

• Self-hosted

• Production-ready

• Secure by default

• Extensible

• Vendor agnostic

• Infrastructure as Code friendly

• Stateless where possible

• Structured outputs only

• Human-auditable

• Open Source

Non-Goals

The project is not intended to become:

• another SSH wrapper

• another Ansible replacement

• another monitoring system

• another Kubernetes operator

Instead, it provides AI-friendly infrastructure primitives built on top of those things.

Three layers, wired top-down:

1. MCP layer (mcp/tools/, mcp/prompts/, mcp/resources/) — registers tools with the MCP SDK. Tools call adapters; they never talk to infrastructure directly.

2. Adapter layer (internal/linux/, internal/docker/, internal/proxmox/, internal/grafana/, ...) — one isolated package per integration, all implementing a common interface. Authentication (SSH keys, API tokens, kubeconfig) lives inside adapters and is never exposed to AI agents.

3. Foundation — internal/inventory/ (YAML config, validated, env-var expansion for secrets) and internal/ssh / internal/telnet (pooled connections to targets, including legacy devices with obsolete crypto or no SSH at all).

Everything is inventory-driven. No IP addresses, hostnames, or credentials appear in tool implementations — targets are resolved by name/tag from the inventory YAML.

Architectural decisions and the reasoning behind them are recorded as ADRs — see docs/adr/.

Installation

Prerequisites

• Go 1.26 or newer (bumped from 1.24 in v0.4 — required by k8s.io/client-go's current release train)

• SSH access (key- or password-based) to the servers/devices you want to manage

• An MCP-capable client (Claude Desktop, Claude Code, Cursor, or any other MCP client)

Build from source

git clone https://github.com/radumalica/infrastructure-mcp.git
cd infrastructure-mcp
go build -o bin/infrastructure-mcp ./cmd/server

Or run via Docker

Pre-built multi-arch images (linux/amd64, linux/arm64) are published to GHCR on every merge to main (see CI/CD):

docker pull ghcr.io/radumalica/infrastructure-mcp:latest

Or with Docker Compose, which wires up the inventory and SSH volume mounts for you — see docker-compose.yaml:

cp configs/inventory.example.yaml inventory.yaml   # fill in your real targets
cp .env.example .env                                # fill in real secrets, never commit
docker compose up -d

Run tests

go build ./...              # build
go vet ./...                # static checks
go test ./... -race -cover  # all tests, race detector, coverage
go test ./internal/linux -run TestName   # a single test

Configuration

The server is entirely inventory-driven — copy the example inventory and fill in your own targets:

cp configs/inventory.example.yaml configs/inventory.yaml

servers:
  archive:
    hostname: 10.0.0.5
    user: hermes
    key: ~/.ssh/archive
    tags:
      - linux
      - ethereum

  pve01:
    hostname: 10.0.0.2
    user: hermes
    proxyjump: jumpbox        # reached only via another inventory target
    tags:
      - proxmox

routers:
  core:
    hostname: 10.0.0.10
    vendor: cisco
    user: admin
    password: ${CORE_ROUTER_PASSWORD}   # resolved from the environment at load time

  legacy-edge:                # no SSH server at all — Telnet only
    hostname: 10.0.0.12
    vendor: cisco
    user: admin
    password: ${LEGACY_EDGE_PASSWORD}
    protocol: telnet

switches:
  ancient-sw:                 # obsolete SSH key exchange/cipher/MAC only
    hostname: 10.0.0.21
    vendor: cisco
    user: admin
    password: ${ANCIENT_SW_PASSWORD}
    legacy_crypto: true

# Every category, including single-instance-feeling ones like Grafana and
# Proxmox, is a map keyed by name — so a second Grafana or a second Proxmox
# cluster is just another key, not a schema change.
grafana:
  main:
    url: https://grafana.lab.local
    token: ${GRAFANA_TOKEN}

proxmox:
  # token is a Proxmox API token in "user@realm!tokenid=uuid" form
  # (Datacenter > Permissions > API Tokens in the PVE UI). Ticket/cookie
  # login is not supported.
  lab:
    url: https://pve.lab.local:8006
    token: ${PROXMOX_TOKEN}

# All auth (client cert, bearer token, exec plugin, ...) lives inside the
# kubeconfig file itself — nothing is inlined into the inventory.
kubernetes:
  home:
    kubeconfig: /etc/infrastructure-mcp/kubeconfig-home
    context: home-admin

Secrets are never written in plaintext. Any ${VAR} in the YAML is resolved from the process environment at load time, and load fails closed if the variable is unset — real credentials are never committed to the repo.

More focused, single-concept inventory fragments (key-authenticated network devices, multi-instance services, ...) live under examples/inventory-snippets/.

Server flags

./bin/infrastructure-mcp \
  -inventory configs/inventory.yaml \
  -known-hosts ~/.ssh/known_hosts \
  -insecure-ignore-host-key=false \
  -transport stdio

Host key verification is fail-closed by default: an unrecognized target's connection is refused unless it's in known_hosts or you explicitly opt into insecure mode. -transport=http is fail-closed the same way: it refuses to start unless the MCP_HTTP_TOKEN environment variable is set (see below) or -allow-anonymous-http is passed explicitly.

Connecting an AI Agent

Infrastructure MCP Server supports two transports from the same binary, so it works with both local-subprocess and remote-network MCP clients:

• stdio (default) — the client spawns the binary itself and talks over its stdin/stdout. This is what most desktop IDEs and agent CLIs (Claude Desktop, Claude Code, Cursor) expect.

• Streamable HTTP (-transport http) — the server listens on the network (/mcp endpoint, plus /healthz) and any remote MCP client connects over HTTP. Use this when the server runs elsewhere (a container, a VM, behind a reverse proxy) rather than on the same machine as the client.

stdio (local)

{
  "mcpServers": {
    "infrastructure": {
      "command": "/path/to/bin/infrastructure-mcp",
      "args": ["-inventory", "/path/to/configs/inventory.yaml"]
    }
  }
}

Remote HTTP

-transport=http requires a bearer token — /mcp exposes every registered tool, including run_command, so the server refuses to start without one (fail-closed, like host key verification above). Generate one and set it as MCP_HTTP_TOKEN:

export MCP_HTTP_TOKEN=$(openssl rand -hex 32)
./bin/infrastructure-mcp -inventory configs/inventory.yaml -transport http -http-addr :8080

(or docker compose up -d, which does this by default once MCP_HTTP_TOKEN is set in .env — see Installation). Every request to /mcp must then send Authorization: Bearer $MCP_HTTP_TOKEN; /healthz stays open for container/load-balancer health checks. -allow-anonymous-http disables this requirement — lab/dev only, never expose an anonymous instance to anything but localhost.

Point any remote-MCP-capable client at http://<host>:8080/mcp with that header set. For clients that only support stdio, bridge with mcp-remote or an equivalent local proxy:

{
  "mcpServers": {
    "infrastructure": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://<host>:8080/mcp", "--header", "Authorization: Bearer ${MCP_HTTP_TOKEN}"]
    }
  }
}

Put the HTTP endpoint behind TLS and network-level access control (a reverse proxy, VPN, or private network) before exposing it beyond localhost — the server itself does not add its own transport-layer authentication.

Once connected, over either transport, the agent sees only the tools listed under Current Features — never raw shell access, never credentials.

Ready-to-adapt client config files (stdio and remote-HTTP-via-mcp-remote) live under examples/mcp-client-config/.

Examples

Full request/response walkthroughs for a few representative tools, run against the inventory shown in Configuration. Values are synthetic — copy the shape, not the data. Every tool's shape is documented in docs/TOOL_REFERENCE.md; runnable inventory fragments and MCP client configs live under examples/.

Check disk space on a server:

disk_usage(server: "archive")

{
  "server": "archive",
  "filesystems": [
    {
      "filesystem": "/dev/sda1",
      "mount_point": "/",
      "total_kb": 51475068,
      "used_kb": 46853200,
      "available_kb": 2003212,
      "used_percent": 91,
      "status": "critical",
      "recommendation": "Free disk space immediately or expand capacity."
    }
  ],
  "timestamp": "2026-07-30T09:00:00Z"
}

List containers on a Docker host:

docker_ps(server: "archive")

{
  "server": "archive",
  "containers": [
    {
      "id": "a1b2c3d4e5f6",
      "image": "grafana/grafana:11.2.0",
      "status": "Up 3 weeks",
      "state": "running",
      "ports": "0.0.0.0:3000->3000/tcp",
      "names": "grafana"
    }
  ],
  "timestamp": "2026-07-30T09:00:00Z"
}

Restart a container — the confirm-gate pattern every mutating tool uses. The first call, without confirm, is a no-op that reports what would happen:

docker_restart(server: "archive", container: "grafana")

{
  "server": "archive",
  "container": "grafana",
  "status": "confirmation_required",
  "message": "Set confirm: true to restart this container. No action was taken.",
  "timestamp": "2026-07-30T09:00:00Z"
}

Only the confirmed call actually restarts it:

docker_restart(server: "archive", container: "grafana", confirm: true)

{
  "server": "archive",
  "container": "grafana",
  "status": "restarted",
  "message": "Container restarted.",
  "timestamp": "2026-07-30T09:00:05Z"
}

Interfaces on a Cisco switch reached over legacy-crypto SSH (legacy_crypto: true in inventory — see ADR 0005):

cisco_interfaces(device: "old-core-sw")

{
  "device": "old-core-sw",
  "interfaces": [
    { "interface": "Vlan100", "ip_address": "10.0.0.23", "ok": "YES", "method": "NVRAM", "status": "up", "protocol": "up" },
    { "interface": "GigabitEthernet1/0/1", "ip_address": "unassigned", "ok": "YES", "method": "unset", "status": "up", "protocol": "up" }
  ],
  "timestamp": "2026-07-30T09:00:00Z"
}

A firing alert from Grafana:

grafana_alerts(instance: "main")

{
  "instance": "main",
  "alerts": [
    {
      "status": "firing",
      "labels": { "alertname": "HighDiskUsage", "instance": "archive", "severity": "critical" },
      "starts_at": "2026-07-30T08:00:00Z",
      "fingerprint": "9f2a1c7e0b3d4e5f"
    }
  ],
  "timestamp": "2026-07-30T09:00:00Z"
}

A tool call against an unreachable target — the structured error envelope, never a raw Go error:

uptime(server: "archive")

{
  "message": "dial tcp 10.0.0.5:22: connect: connection refused",
  "recommendation": "Retry the request; if it persists, check network connectivity to the target.",
  "retryable": true,
  "category": "network"
}

Tool Design Philosophy

Never expose raw infrastructure:

execute(command)     # avoid

Prefer meaningful, structured actions:

check_disk()
check_memory()
docker_list()
grafana_alerts()
backup_switch()

Every tool:

• validates its inputs

• never panics

• returns structured JSON

• includes severity where relevant

• includes a recommendation on warning/critical states

• includes a timestamp

{
  "status": "warning",
  "server": "archive",
  "disk_usage": 91,
  "recommendation": "Free disk space or expand storage.",
  "timestamp": "2026-07-23T19:10:00Z"
}

Logging

Every tool execution produces a structured log line with:

tool, user, duration, target, result, error

Error Handling

Tools never return a raw Go error. Every failure is shaped as:

message, recommendation, retryable, category

(category is one of not_found, auth, network, timeout, invalid_input, internal.)

Security

• No secrets in logs

• No secrets in prompts

• No shell interpolation — any user-supplied value that reaches a remote command is validated against a strict whitelist pattern first

• Validate all inputs

• Whitelist inventory — no target is reachable unless it's named in the inventory

• Least privilege

• Read-only by default

• Dangerous actions require explicit confirmation (e.g. docker_restart requires confirm: true and is a no-op otherwise)

• -transport=http is fail-closed: it refuses to start without a bearer token (MCP_HTTP_TOKEN) unless -allow-anonymous-http is explicitly passed

Found a security issue? Please report it privately rather than opening a public issue — see Contributing.

Development

Testing standards

• Unit tests target ~100% coverage for inventory, adapters, parsing, and validation

• Integration tests use Testcontainers / Docker Compose (Ubuntu, Alpine, Grafana, Prometheus, Loki)

• Every tool is exercised through a real MCP protocol round-trip (mcp.NewInMemoryTransports()), not just unit-tested in isolation

Performance goals

• SSH/Telnet connection pooling

• Parallel execution

• Context cancellation everywhere

• Streaming responses

• Timeout and retry support

Code conventions

• Small packages, dependency injection, no globals, prefer interfaces

• context.Context everywhere

• log/slog for logging

• Avoid reflection when possible

• Functions under ~50 lines when practical

• Structured errors, never raw ones

• Document exported functions

• Never expose credentials to the MCP layer

• Never hardcode infrastructure — always resolve through inventory

Adding a new integration? See docs/ADDING_AN_ADAPTER.md for the full walkthrough.

CI/CD

Two GitHub Actions workflows, both required for anyone contributing:

ci.yml — required for every PR into main

Runs on every pull request and on push to main:

• test — go build ./..., go vet ./..., a gofmt -l formatting check, and go test ./... -race -cover

• lint — golangci-lint against .golangci.yml (errcheck, staticcheck, govet, gosec, and more)

Branch protection on main must be configured by a repo admin (this is a repository setting, not something a workflow file can enforce) to require both the test and lint jobs to pass, and to require a pull request before merging — that gate only takes effect once the setting is turned on.

The release pipeline is designed to work with protected main: it creates and pushes only the release tag, creates the GitHub release from that tag, and opens a separate PR for CHANGELOG.md updates.

release.yml — runs on every merge to main

1. Version + tag — Cocogitto reads Conventional Commits since the last tag (config: cog.toml) and computes the next semver. The workflow then creates and pushes the vX.Y.Z tag (no direct commit push to main). A merge with no releasable commits (e.g. docs/chore-only) skips the rest of the pipeline.

2. Build & scan — builds the Docker image and scans it with Trivy before publishing; a CRITICAL/HIGH finding blocks the release. Results are uploaded to the repo's Security tab either way.

3. Publish — once the scan is clean, builds and pushes the multi-arch (linux/amd64, linux/arm64) image to ghcr.io/<org>/infrastructure-mcp, tagged latest and vX.Y.Z.

4. Changelog PR — the workflow regenerates CHANGELOG.md and opens an automated PR so changelog updates still go through normal branch protection and review.

Commit messages therefore need to follow Conventional Commits (feat:, fix:, docs:, chore:, ...) — see Contributing.

Roadmap

Shipped: Linux · Docker · Kubernetes · Grafana · Proxmox · Cisco Not started: MikroTik · UniFi · Prometheus/Loki/Tempo/Alertmanager · Home Assistant · AI-composite tools · AWS/Azure/GCP/VMware/...

Implemented versions are listed under Current Features and tracked feature-by-feature in PROGRESS.md. Everything below is not started.

v0.7 — Networking (in progress: Cisco shipped, MikroTik/UniFi remain)

MikroTik: backup, interfaces, routes, firewall, system resources UniFi: devices, clients, AP status, firmware, statistics

Note: Telnet transport and SSH legacy-crypto support for these vendors already shipped ahead of schedule in v0.1 — only the vendor-specific tools above remain.

v0.8 — Monitoring

Prometheus, Loki, Tempo, Alertmanager

v0.9 — Home Assistant

• entities

• devices

• automations

• sensors

• cameras

v1.0 — AI-oriented composite tools

Instead of calling 15 low-level tools, the agent calls one expert tool that composes them:

• diagnose_linux()

• diagnose_docker()

• diagnose_kubernetes()

• diagnose_network()

• diagnose_storage()

• morning_brief()

• incident_summary()

• root_cause_analysis()

• backup_everything()

• check_infrastructure()

Further out

AWS, Azure, GCP, VMware, TrueNAS, Ceph, Synology, IPMI, Redfish, OpenStack, Nomad, Consul.

Contributing

Contributions are welcome — this is an early-stage project and there's a lot of surface area left on the roadmap above.

1. Fork the repo and create a feature branch.

2. Follow the existing package/adapter pattern: one isolated package per integration under internal/, a matching set of tools under mcp/tools/, wired into cmd/server/main.go — see docs/ADDING_AN_ADAPTER.md for the full walkthrough.

3. Match the existing conventions: structured errors via internal/toolerr, structured logging via the withLogging wrapper, inventory-driven targets, no shell interpolation of user input.

4. Add tests — unit tests for adapters/parsing, and at least one test that exercises new tools through the real MCP protocol.

5. Run go build ./... && go vet ./... && gofmt -l . && go test ./... -race -cover and, if you have it installed, golangci-lint run ./... before opening a PR — this is exactly what ci.yml runs, and it's a required, non-optional check on every PR into main (see CI/CD).

6. Use Conventional Commits for your commit messages (feat:, fix:, docs:, chore:, refactor:, test:, ci:, ...) — the version bump, CHANGELOG.md, and release on merge are generated automatically from them.

7. Open a pull request describing what changed and why. For an architectural decision (not just "add tool #N following the existing pattern"), add an ADR under docs/adr/.

For larger changes (a new adapter, a new version's worth of tools), consider opening an issue first to discuss the approach.

A Note on How This Project Is Built

This project is vibe-coded: the vast majority of the implementation — code, tests, commit-by-commit progress — is written by AI (Claude Code), iterating directly against this README as the specification.

The design and architecture are human-authored by the repository owner: the layering (MCP → adapters → foundation), the inventory-driven philosophy, the tool-design rules, the security posture, and the version roadmap were all decided by a person before any code was written. AI implements against that spec; it doesn't set the direction.
