All 35,800 entries in the list, with filters and pagination

Newest in this category

The 10 entries of this category that this registry listed most recently for the first time and that are not shown above. Ordered by the day first listed, not by any rating.

How it works

Before choosing

The selection depends on whether the source declares an environment variable or HTTP header as both secret and required. The absence of such a declaration proves neither access without an account nor a free service. Check the variables listed in the entry and the provider’s instructions before setting it up.

derived from: Required secret variables (raw)

A derived value carries its original data beside it; the derivation rule is published, with a version, on the methodology page.

Caveats, distribution and query

What this category does not say

  • Required secrets declared is not declared but computed: from Required secret variables (raw), Required secret headers (raw). The rule is published, with a version, on the methodology page.

What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

Every sentence here follows from the condition above, not from an assessment.

Per property, the measured values inside this category. The share refers to the 35,800 entries of the category, not to the registry. Shown are 6 of 7 properties: those whose values spread the most inside this category.

The same category through the interface

curl -s "https://api.tracevero.com/v1/eintraege?art=mcp_server&zugangsdaten_erforderlich=false&grenze=200"

The command carries exactly the condition of this page. 35,800 entries at 200 each are 179 requests; the total is in the X-Gesamt header.

Both addresses narrow the change stream to exactly the entries in this category. The feed carries an identifier of its own, so a feed reader keeps it apart from the full stream.

Questions about this selection

How do I set up one of these servers in my client?

Open the entry and choose “Build configuration” when a launch template is available. The builder lists the supported clients and identifies the values you need to supply. A generated file does not establish that the server is reachable or works with your installation.

View clients and setup

Are the listed servers free?

Membership of this category says nothing about price. Neither a repository address nor the absence of declared required secrets establishes that a service is free. Check the individual provider’s pricing and access terms.

How can I follow changes to this selection?

Each entry identifies the source and collection date of its declarations. The change stream for this category shows published changes to its entries. You can subscribe to its Atom feed without creating an account.
