Find a fit. Read the reasoning.
Alphabetical by default. Every match is shown.
Compare up to three before opening a full review.
80 of 80 selected mcp servers
Spreadsheet automation · PSU3D0
Agent Spreadsheet MCP
Provides workbook inspection and structured edit/recalculation workflows through a Rust MCP server with a configured workspace root.
Why we selected itExposes structured workbook operations and revision-aware workflows instead of relying entirely on screen automation.
Weigh upHTTP has no built-in authentication and binds to loopback by default; keep it local or add an appropriate access layer.
Framework development · Angular
Angular CLI MCP
Angular CLI tools for workspace discovery, framework guidance and explicitly permitted build or test operations.
Why we selected itKeeps workspace discovery and framework-specific guidance close to the CLI that owns the project.
Weigh upThe read-only and local-only flags filter registered tools; neither is an operating-system sandbox or a restriction on the host’s other tools.
Planning and collaboration · Asana
Asana MCP V2
Asana’s current workspace-scoped MCP connection for task, project and portfolio workflows.
Why we selected itUses the current V2 endpoint and registered OAuth app flow, with a session tied to the selected workspace.
Weigh upStandard write tools execute immediately; a confirmation interface exists only for supported interactive tools and hosts.
Team collaboration · Atlassian
Atlassian Rovo MCP
Searches connected Atlassian work and lets an authorized client create or update work items and pages through the current Rovo MCP endpoint.
Why we selected itConnects Jira and Confluence work with related Atlassian context in a single documented service.
Weigh upActions use the authenticated user’s existing access across connected products.
Workspace knowledge · Atuin
Atuin MCP
Let an agent search your shell history and retrieve captured command output without executing those commands.
Why we selected itHistory results connect a command with its directory, exit status and a reusable history identifier.
Weigh upShell history and terminal output can contain sensitive data; local storage does not stop the MCP client from sending results to a model provider.
Infrastructure validation · AWS Labs
AWS IaC MCP Server
Validates CloudFormation templates, retrieves CDK/CloudFormation guidance and investigates failed deployments.
Why we selected itCombines template validation and compliance checks with source documentation for the same infrastructure workflow.
Weigh upValidation and compliance results do not certify a template or deployment as safe.
Documentation search · Amazon Web Services
AWS Knowledge MCP
Retrieves official AWS documentation, regional availability and task guidance without granting access to an AWS account.
Why we selected itKeeps documentation retrieval separate from credentialed AWS control-plane tools.
Weigh upThe service is rate-limited and needs network access.
Cloud operations · Microsoft
Azure MCP Server
Brings Azure service tools into one MCP server, with namespace selection and a read-only option for scoped use.
Why we selected itProvides Azure-specific operations through one maintained implementation rather than unrelated adapters.
Weigh upThe documented default readOnly setting is false; enabled tools can create or change cloud resources.
Web search · Brave
Brave Search MCP
Provides web, news, image, video and place search using the Brave Search API.
Why we selected itA publisher-maintained replacement for the archived reference Brave adapter.
Weigh upSearch queries are sent to Brave and API account limits apply.
Design and content · Canva
Canva MCP
A hosted connection for authorized Canva design discovery, creation, editing and export workflows.
Why we selected itConnects design operations to existing Canva accounts and asset permissions rather than claiming unrestricted access to brand content.
Weigh upPer-user authorization and existing design permissions apply. Some design, resize, brand or autofill features depend on the user’s plan and organization setup.
Vector data management · Chroma
Chroma MCP
Lets an assistant create and query Chroma collections through local, HTTP or Chroma Cloud database connections.
Why we selected itDocuments collection and document operations rather than claiming retrieval alone.
Weigh upThe default client is ephemeral; persistence requires explicit configuration.
Browser diagnostics · Google / Chrome DevTools
Chrome DevTools MCP
Records browser performance traces and inspects live page, console and network behavior from an MCP client.
Why we selected itAdds live performance tracing and diagnostic insights alongside browser automation, complementing the separate Playwright and Perfetto selections.
Weigh upThe connected assistant can inspect and modify browser content. The documented default uses a persistent browser profile; use --isolated when launching Chrome with a temporary profile and avoid unrelated sensitive sessions.
Analytics databases · ClickHouse
ClickHouse MCP Server
Queries ClickHouse and inspects table metadata, with read-only SQL by default and separate authentication for network transports.
Why we selected itDocuments query permissions and HTTP caller authentication separately.
Weigh upRead-only queries can still consume substantial database resources.
Cloud operations · Cloudflare
Cloudflare API MCP
Lets an assistant discover Cloudflare API endpoints and execute API calls through code, within the granted Cloudflare permissions.
Why we selected itAPI discovery and execution share one source-backed workflow, including documentation lookup.
Weigh upThe execute tool can change Cloudflare resources; this is a broad account-control surface.
Documentation search · Cloudflare
Cloudflare Documentation MCP
Searches Cloudflare documentation without granting an assistant access to a Cloudflare account.
Why we selected itSeparates documentation lookup from account-changing Cloudflare servers.
Weigh upSearch queries leave the client for Cloudflare’s hosted service.
Media management · Cloudinary
Cloudinary Asset Management MCP
Search, upload, organize and transform Cloudinary media through its dedicated Asset Management server.
Why we selected itProvides media-specific search, organization and transformation operations from a single reviewed endpoint.
Weigh upAsset tools can upload, rename or delete media; grant access only to the intended cloud.
Content management · Contentful
Contentful MCP
Read and manage Contentful entries, assets, content types and environments through its local MCP server.
Why we selected itExposes structured CMS operations rather than treating a content space as an unstructured document store.
Weigh upPublishing, unpublishing, deletion and environment operations are available; the server is not an editorial approval system.
Developer documentation · Upstash
Context7 MCP
Resolves a library identity and retrieves documentation relevant to a specific coding question through Context7's hosted index.
Why we selected itSeparates library identification from documentation retrieval, making the selected upstream library visible before an answer is assembled.
Weigh upDocumentation projects are community-contributed; the publisher does not guarantee their accuracy, completeness or security.
Observability · Datadog
Datadog MCP
Query Datadog telemetry and operate permitted monitoring resources from an authenticated AI client.
Why we selected itConnects logs, traces, metrics, incidents and monitoring context already held in Datadog.
Weigh upMCP read/write permissions are additional to resource permissions; this is not a read-only connector by default.
Analytics engineering · dbt Labs
dbt MCP Server
Connects dbt project metadata and lineage with optional local CLI, Semantic Layer and Platform operations.
Why we selected itSupports both project understanding and concrete build/test/job workflows.

Vector memory · Qdrant
Qdrant MCP Server
Stores and retrieves semantic memories in Qdrant, with a switch that removes the storage tool for retrieval-only use.
Why we selected itThe small find/store tool surface makes its data effects easy to identify.
Weigh upStorage is enabled by default; QDRANT_READ_ONLY must be set for retrieval-only use.
Cache and data operations · Redis
Redis MCP Server
Exposes Redis data-type operations and search to an MCP client using Redis credentials and ACLs.
Why we selected itProvides Redis-specific operations rather than reducing every task to an arbitrary command string.
Weigh upThe implemented/documented transport is stdio; Streamable HTTP is listed as future work.
Cloud operations · Render
Render MCP
Inspect Render services, logs and metrics, query Postgres, and perform supported deployment operations.
Why we selected itProvides a hosted first-party endpoint with workspace-scoped operations.
Weigh upDeployment and environment-variable tools can change live services; read-only SQL does not make the whole server read-only.
Email operations · Resend
Resend MCP
Connects an assistant to Resend email sending, delivery records and account operations through hosted or local MCP.
Why we selected itAdds a concrete outbound-email workflow, including message inspection and scheduled-email operations.
Weigh upThis is broader than an email drafting tool: enabled operations can send real messages and administer contacts, broadcasts, domains and API keys.
Detection engineering · Timescale
RSigma MCP
Exposes Sigma rule parsing, linting, evaluation and conversion, with separately enabled incident-triage and operational-write tools.
Why we selected itSupports a concrete rule-authoring loop with structured parse, lint and evaluation results.

Weigh upRead-only mode is opt-in; the standard connection includes mutating capabilities.
Framework development · Svelte
Svelte MCP
Official Svelte documentation and static-analysis tools, available as a local process or a hosted MCP endpoint.
Why we selected itCombines version-relevant documentation discovery with analysis of Svelte components and modules.
Weigh upThe autofixer returns issues and suggestions; it does not itself apply a patch or prove the application works.
Web research · Tavily
Tavily MCP
Combines web search, extraction, mapping and crawling through local stdio or Tavily’s hosted MCP service.
Why we selected itDocuments both lightweight search/extract use and broader crawl/map workflows.
Weigh upKeyless mode is limited; crawl/map and broader usage need an authenticated account.
Infrastructure development · HashiCorp
Terraform MCP Server
Looks up Terraform Registry documentation and can manage HCP Terraform or Terraform Enterprise workspaces and runs.
Why we selected itCombines provider/module documentation with separately credentialed workspace operations.
Weigh upHCP/TFE workspace tools include creation, updates and deletion; registry lookup does not imply a read-only server.
Task planning · Doist
Todoist MCP
Reads and changes Todoist tasks, projects and schedules through Doist’s hosted service or local server.
Why we selected itAdds personal and team task planning, including due dates and rescheduling, beyond software issue tracking.
Weigh upThe toolset can create, update, complete and delete account data. Deletion hints inform a client but are not a human approval gate.
Secrets administration · HashiCorp
Vault MCP Server
Lets a trusted MCP client operate Vault secrets and mounts using a configured Vault identity.
Why we selected itProvides an inspectable integration for a specific secrets-management workflow.
Weigh upThis server can disclose secrets to the client and model; it is unsuitable as a general public MCP endpoint.

03 / BEHIND THE SELECTION
The review is part of the product.
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.

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.
