Sonatype Nexus MCP Server

A Model Context Protocol server that lets AI assistants inspect, audit and document a Sonatype Nexus Repository Manager 3.x instance. It is read-only by default; administrative tools are not even listed unless you enable them.

flowchart LR

AI[MCP client] <-->|stdio / Streamable HTTP| Server[nexus-mcp-server] Server <-->|REST API| Nexus[Nexus Repository 3.x]

Features

Inventory of repositories, blob stores, tasks, cleanup policies, routing rules, content selectors, users, roles and privileges, as far as the configured account can see them.
A relationship graph (repository → blob store, group → members, repository → cleanup policy, role → privilege) behind architecture explanations, risk checks and generated Markdown documentation.
Bounded full-content audit of one repository, with completion evidence.
Drift check of repositories against a declared state.
OpenAPI discovery of the instance's REST operations.
Every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint; outputs and logs redact the configured password and secret-looking keys.
Starts without configuration, so clients and registries can list its tools; calls then report what is missing.

Used in production in read-only mode on Nexus Pro 3.96.1-01; partially verified on OSS 3.70. See docs/COMPATIBILITY.md.

Quick start

The server is listed in the MCP Registry as io.github.oomchiller/nexus-mcp-server; registry-aware clients can install it from there. Manual setup:

Container

docker run --rm -i \

-e NEXUS_URL=https://nexus.example.com \ -e NEXUS_USERNAME=readonly-user \ -e NEXUS_PASSWORD \ ghcr.io/oomchiller/nexus-mcp-server:0.2.1

Images are published for linux/amd64 and linux/arm64, run as an unprivileged user over stdio, and are configured through the environment only. Release digests are listed on the releases page.

Local process

"mcpServers": { "nexus": { "command": "uvx", "args": ["--from", "git+https://github.com/oomchiller/nexus-mcp-server@v0.2.1", "nexus-mcp-server"], "env": { "NEXUS_URL": "https://nexus.example.com", "NEXUS_USERNAME": "readonly-user", "NEXUS_PASSWORD": "change-me" } } } }

More client examples (Claude Desktop, Codex CLI, Gemini CLI) are in examples/.

Configuration

Settings come from the environment or a .env file in the working directory.

Variable	Default	Meaning
`NEXUS_URL`	unset	Nexus base URL. Without it the server starts, and calls report that Nexus is not configured.
`NEXUS_USERNAME` / `NEXUS_PASSWORD`	unset	Basic authentication. Use a read-only Nexus account.
`NEXUS_VERIFY_TLS`	`true`	Verify the Nexus TLS certificate.
`NEXUS_CA_BUNDLE`	unset	PEM file of CA certificates to trust instead of the public roots; needs `NEXUS_VERIFY_TLS=true`.
`NEXUS_TIMEOUT_SECONDS`	`30`	HTTP timeout.
`NEXUS_ALLOWED_HOSTS`	host of `NEXUS_URL`	Comma-separated hosts the client may contact.
`NEXUS_LOG_LEVEL`	`INFO`	Log level (stderr).
`NEXUS_MCP_MODE`	`readonly`	`readonly`, `audit` (same gates as `readonly`) or `admin`.
`NEXUS_MCP_ENABLE_WRITE_TOOLS`	`false`	With `admin`, lists and allows the write tools.
`NEXUS_MCP_ENABLE_RAW_API`	`false`	Lists `nexus_api_call`.
`NEXUS_MCP_RAW_API_GET_ONLY`	`false`	Restrict `nexus_api_call` to `GET`.
`NEXUS_MCP_MAX_RAW_RESPONSE_BYTES`	`1048576`	Largest Nexus response accepted.
`NEXUS_MCP_GRAPH_TTL_SECONDS`	`60`	How long graph tools reuse one Knowledge Graph build; `0` rebuilds on every call.
`NEXUS_MCP_ENABLE_PROMPTS`	`true`	Register prompts.
`NEXUS_MCP_ENABLE_RESOURCES`	`true`	Register resources.

Token authentication is not implemented.

The server does not read SSL_CERT_FILE or the system trust store. For a Nexus behind a private CA, set NEXUS_CA_BUNDLE rather than disabling verification. An unreadable bundle, or a bundle with verification disabled, stops the server at startup.

Gateways that run several instances side by side and prefix only tool names (Docker MCP Gateway) should set NEXUS_MCP_ENABLE_PROMPTS=false and NEXUS_MCP_ENABLE_RESOURCES=false.

Command line

--transport {stdio,sse,streamable-http}   default stdio

--host HOST / --port PORT HTTP bind, default 127.0.0.1:8000, no authentication --nexus-url URL overrides NEXUS_URL --nexus-username USERNAME overrides NEXUS_USERNAME --verify-ssl / --no-verify-ssl overrides NEXUS_VERIFY_TLS --ca-bundle PATH overrides NEXUS_CA_BUNDLE

Keep NEXUS_PASSWORD in the environment, not on the command line.

Listed only when enabled:

Tool	Requires
`nexus_api_call`	`NEXUS_MCP_ENABLE_RAW_API=true`; paths are canonicalized and restricted to `/service/rest/`.
`nexus_delete_repository`, `nexus_run_task`	`NEXUS_MCP_MODE=admin` and `NEXUS_MCP_ENABLE_WRITE_TOOLS=true`.

Resources: nexus://instance/summary, nexus://repositories, nexus://blobstores, nexus://tasks, nexus://cleanup-policies, nexus://security/summary, nexus://architecture, nexus://knowledge_graph. Prompts: nexus_audit_prompt, nexus_iac_drift_prompt.

Limits worth knowing: drift compares repository name, format and type only; risk checks cover a small set of graph rules; findings are only as complete as the REST APIs visible to the account. Optional endpoints that are missing for version, edition or permission reasons appear as limitations, not failures.

Safety

Read-only by default. Write tools and the raw API are not listed unless enabled, and every write is still checked against the mode at call time.
The client contacts only NEXUS_ALLOWED_HOSTS and only paths relative to NEXUS_URL.
Redaction is defence in depth, not a substitute for a least-privilege Nexus account. See SECURITY.md.
