Self-hosted Snyk MCP alternatives
Snyk's server lives inside the Snyk CLI and runs locally, scanning dependencies, code, containers, and IaC right on the machine where code is written, so the source never has to leave your environment to be checked. If keeping the scanner and its credentials local is the point, the alternatives below install the same way.
Each one ships a local command over stdio. A note on what that buys you: a local server keeps the process and tokens on your infrastructure, but a connector pointed at a cloud account or hosted backend still sends its requests there. The scanners that read your code or files keep the most local; the cloud and observability connectors reach out to their respective platforms.
The 8 best self-hosted alternatives
- SemgrepOfficial
Semgrep's server runs locally and scans code for security vulnerabilities, runs custom rules, and pulls findings, reading your source on the same machine the way Snyk's code scan does.
Set up Semgrep → Any AWS CLI command runs through AWS Labs' server with validation and a read-only mode from a local process, reaching security and config services in an account you administer.
Set up AWS (AWS Labs) →Watching what gets past a scan fits a self-hosted Grafana: the server installs over stdio and queries dashboards, Prometheus, and Loki, plus incidents and alerts.
Set up Grafana →Sentry's server runs locally and pulls issues, stack traces, and events, with Seer root-cause analysis, catching runtime errors on a process you control.
Set up Sentry →Pointed at a Prometheus you operate, this server runs PromQL instant and range queries, discovers metrics, and inspects scrape targets, all from a local command against your own server.
Set up Prometheus →Traces, logs, metrics, dashboards, and alerts come from the SigNoz server, which installs locally for an OpenTelemetry-native stack you run yourself.
Set up SigNoz →Run over stdio, the PagerDuty server exposes incidents, services, schedules, teams, and orchestrations across 64 tools, read-only by default, keeping on-call routing on a local process.
Set up PagerDuty →- AzureOfficial
For teams on Azure, Microsoft's server runs locally and manages 40+ services, storage, Key Vault, Cosmos DB, SQL, Monitor, AKS, and more, the cloud-account side of the picture.

How to choose
All of these install over stdio, so the process and credentials stay on your infrastructure. Semgrep is the direct security peer, reading code locally like Snyk. AWS and Azure reach a cloud account you administer, while Grafana, Sentry, Prometheus, SigNoz, and PagerDuty cover runtime monitoring and incidents. Code and file scanners keep the most local; cloud and observability connectors still talk to their platforms.
FAQ
- Can the Snyk MCP server be self-hosted?
- Yes. Snyk's server is built into the Snyk CLI and runs locally, so the scanner process and its credentials stay on the machine where you write code, and the source does not have to leave to be checked.
- Does running these locally keep my code and data on my own infrastructure?
- It keeps the MCP process and credentials local. Semgrep reads your code on the same machine, but the cloud connectors like AWS and Azure send requests to those accounts, and the observability servers query their backends unless you self-host them too.
