Test review Inspect the tests independently; name missing behaviours and reproduction steps. ### Then work in this order - Configure read-only GitHub toolsets, retrieve a fixed revision and define the review scope. Keep the original requirements next to the diff. - Run independent bug and test reviews against that same revision. Do not let one reviewer supply the other’s verdict. - Reconcile overlapping findings, verify the material ones, and write a single review. Make changes only after that review is checked. ### Keep these boundaries - Choose a host for each stage and verify its tool mapping. Pass evidence explicitly between stages; the listed resources do not automatically configure or invoke one another. - A compatible host and GitHub authentication are separate setup steps. Definitions do not configure MCP tool names automatically. - Request only repository access needed for the review. Do not submit comments, change issues or workflows, edit files or merge during evidence collection. Enable write tools only for a separately authorised task.

Go stdio **Why we selected it**Brings dependency and package-health investigation together with source and configuration scans. **Weigh up**Dependency scans may run ecosystem tools such as Gradle or Maven; a read-only scan annotation is not a no-execution guarantee.

TypeScript Streamable HTTP **Why we selected it**Documents project scoping and feature selection alongside a read-only mode. **Weigh up**Read-only mode is opt-in; the standard connection includes mutating capabilities.

TypeScript stdio Streamable HTTP **Why we selected it**Combines version-relevant documentation discovery with analysis of Svelte components and modules. **Weigh up**The autofixer returns issues and suggestions; it does not itself apply a patch or prove the application works.

Go stdio Streamable HTTP **Why we selected it**Provides an inspectable integration for a specific secrets-management workflow. **Weigh up**This server can disclose secrets to the client and model; it is unsuitable as a general public MCP endpoint.

A useful recommendation tells you why it fits—and what still needs checking. ### What we inspect We review publisher documentation and the implementation or configuration material named on each page. We examine useful scope, installation, authentication, tool permissions and limitations. A registry entry proves discovery, not security, runtime compatibility or a universal quality ranking. ### What a selection means Each resource has a concrete use case, original selection reasons, named limitations and a dated review record. We favour specific instructions, useful scope and inspectable setup. The list is curated; it is not a census of everything available or an independently benchmarked league table. ### Before using it Read the complete review, check the upstream revision and match the resource to your own host and permissions. Review notes apply to the material named at the recorded date. Installation commands may retrieve a newer upstream version. ### Where we looked - Official MCP Registry ↗ Discovery and package/remote identities; listing is not a quality or security endorsement. - MCP reference server repository ↗ Reference-server and archived-server lifecycle cross-check; educational reference implementations were not assumed production-ready. - Awesome MCP Servers ↗ Independent discovery only; badges and self-reported performance claims are not adopted. - npm package registry ↗ Public package manifests cross-checked package identity; download counts were not used as quality evidence. - Python Package Index ↗ Public package metadata supplements publisher source manifests; no package was installed. - crates.io ↗ Rust package metadata cross-checks the selected package identities; no binaries were installed or run. - Publisher-maintained repositories and official service documentation ↗ Each candidate was resolved to its publisher sources; record-level citations and receipts contain the exact reviewed paths/revisions. - Publisher-source expansion review ↗ - Hugging Face official MCP guide ↗ - Slack official MCP guide ↗ - Svelte primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Google Analytics primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Angular primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Firebase primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Salesforce primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Perplexity primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - PagerDuty primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Asana primary source ↗ Direct source screening; popularity was not treated as evidence of quality. - Canva primary source ↗ Direct source screening; popularity was not treated as evidence of quality. [Download this index as JSON ↗](/data/resources/mcp-servers.json) Selections we withheld (9) These are documented decisions from this review, not a blacklist of the wider ecosystem. - **Archived MCP reference integrations:** The official repository marks the old GitHub, PostgreSQL, Brave, Redis, Sentry and other reference integrations archived. They are not selected as current product integrations. Source ↗ - **Reference implementations as production endorsements:** The maintained reference repository explicitly describes its examples as educational, not production-ready solutions. No safety or production-readiness endorsement is inferred. Source ↗ - **elastic-legacy:** The standalone Elasticsearch MCP server is deprecated and receives only critical security updates; use the documented Agent Builder successor. Source ↗ - **snowflake-legacy:** Snowflake-Labs/mcp is explicitly deprecated and no longer maintained; the current service is Snowflake-managed MCP. Source ↗ - **notion-legacy:** The official setup guide says the older notion-mcp-server adapter is no longer actively maintained; it is not the hosted OAuth service. Source ↗ - **generic-gateways:** Discovery also found generic Rust gateways and unrestricted shell/file proxies. They were not selected merely to increase language or server counts. Source ↗ - **Legacy standalone Semgrep MCP repository:** The publisher archived this standalone repository and moved MCP development into the main Semgrep CLI. Its old package/install instructions were not selected; this is not a finding that the current Semgrep MCP implementation is retired. Source ↗ - **Deprecated standalone Weaviate MCP:** The publisher marks the standalone implementation deprecated and no longer maintained. The selected Weaviate record covers the current built-in database endpoint. Source ↗ - **RustFS MCP setup with missing source target:** Current official documentation warns that rustfs-mcp is no longer in the main repository and its shown build commands may fail. A current implementation and reproducible setup were not established in this review. Source ↗ 04 / PRACTICAL ANSWERS ## Before you add it. What is an MCP server? An MCP server exposes capabilities to a compatible AI client through the Model Context Protocol. Depending on the server, these may include tools, data resources or prompts. A local subprocess and a remote hosted endpoint have different setup and access requirements. Does source review mean a server is safe? No. The review records what was inspected and what remains untested. Credentials, exposed tools, connected accounts, host permissions and deployment configuration determine what a server can access or change. Review those boundaries for your own environment. Can I paste the same configuration into every client? No. Clients differ in configuration format, supported transports and authentication behavior. Any example on a detail page retains its documented context; the linked setup guide is the source for the intended client. Replace credential placeholders through the client’s supported secret mechanism. Why include different programming languages? Implementation language can matter for installation, deployment and source inspection. It does not establish server quality on its own. Use the language, transport and purpose filters to narrow your operational fit, then read the review and setup requirements.
