Directory of MCP Servers

coderstartup•6h ago
Super cool, Thanks
Maxious•4h ago
There's some movement on https://github.com/modelcontextprotocol/registry

> The MCP Registry service provides a centralized repository for MCP server entries. It allows discovery and management of various MCP implementations with their associated metadata, configurations, and capabilities.

connor4312•3h ago
@ VS Code we've been collaborating on this and plan to ship initial support for registries in our next release.
mooreds•4h ago
Also interesting was mintlify's decision to start one and then shut it down.

https://mintlify.com/blog/why-we-sunsetted-mcpt

Nice story of startup focus.

asdev•4h ago
You don't need MCP you just need function calling
laidoffamazon•4h ago
Is there a better “universal” or standard framework to do itv
asdev•4h ago
you don't need any universal standard, you just need functions specific to your app's use case
djohnston•2h ago
you can leverage MCPs without building any app at all.
hughdbrown•4h ago
Yeah, but there is a distinct advantage to using a standard.

Suppose you want your agent to use postgres or git or even file modification. You write your code to use MCP and your backend is already available. It's code you don't have to write.

jappgar•2h ago
Are we still writing code?
mindwok•3h ago
Yes because we should all be building function calling implementations for the same 10 SaaS services rather than using 10 standard MCP servers.
ukuina•1h ago
But the standard servers should be hosted by the service provider, like mcp.slack.com as a counterpart to api.slack.com

Why should I be self-hosting ANY local MCP server for accessing an external service?

reustle•57m ago
That is being done as a stop gap until official servers are released. Ideally you are writing a server for your own product/service, or custom local work.

i.e. I wrote a server for water.gov to pull the river height prediction nearby for the next 24hr. This helps the campground welcome message writing tool craft a better welcome message.

Sure that could be a plain tool call, but why not make it portable into any AI service.

jappgar•2h ago
I find it funny that vibers trust AI to write their entire platform but don't trust it enough to eval a curl statement.
devops000•4h ago
What is a useful agent build with MCP?
kordlessagain•3h ago
I have an agent that creates new tools here: https://github.com/kordless/gnosis-evolve. I use it with Claude Desktop for a lot of different things, including browsing or searching for content, with the various crawlers that are out now. There's a crawl4ai tool that is pretty useful.
reustle•3h ago
Here are a few more:

- https://smithery.ai/

- https://github.com/wong2/awesome-mcp-servers

- http://mcp.so/servers

- https://cursor.directory/mcp

But as mentioned above, there is an ongoing discussion for the Anthropic registry https://github.com/modelcontextprotocol/registry

tkellogg•2h ago
FYI https://mcp.so/ is the exact same thing as was posted. Not sure why they directed to the github instead of the actual site..
cadamsdotcom•3h ago
There's a huge gap in this market for someone who can take these and make them trustworthy. Maybe the OpenRouter of MCP.
tough•3h ago
The underlying issue is always relying on a third party, on openrouter you're trusting the end model provider to not do funny business

can't really fix this

cadamsdotcom•1h ago
If you're paying said third party it's a decent mitigation.
cyanydeez•3h ago
I don't see how they could ever be trust worthy without kneecaping the claimed benefits.
jjfoooo4•3h ago
I’ve been seeing MCP compared to extensions in web browsers. Which I find telling, since I wouldn’t exactly say web extensions have been a great success - it’s a pretty niche dev market, and the security posture remains pretty anxiety inducing

Model Context Protocol
CSMastermind•2h ago
I wonder if there's a market for someone figuring out how to build monetization into MCP or something similar.

Being able to offer a helpful API to the world and just getting paid whenever someone uses it would be really nice.

At the moment you have to process the payment "yourself" (even if you use a third party for that), issue an API key, etc.

meander_water•1h ago
I reckon the target market would have to be non-developers (because MCP servers are easily reproducible with LLMs, they even encourage it in the docs), and you wouldn't even mention MCP. Just have a list of tools which you can optionally enable in the chat client
jappgar•2h ago
Is this like 10 years ago when you could find a Directory of GraphQL Servers?

Seems silly in retrospect no?

malablaster•11m ago
I agree. There’s no need to centralize this list.
schappim•1h ago
So far, I’ve catalogued over 6,000 MCP servers.

If you’re interested in the next layer beyond just discovering MCP servers, I’ve been working on https://ninja.ai — an app store for AI assistants to connect to tools via MCP, without needing to touch the command line. Think one-click installs for pipes that let agents actually do things like triage email or book Ubers.

Would love feedback if you’re experimenting in this space too!

Nedomas•1h ago
We've built a version of this on steroids - not only a registry, but also one-click mcp hosting. Would love you eyeballs if you're into mcp: https://supermachine.ai
maxwellg•14m ago
I can't wait for first-party remote MCP servers to become more common. Right now we're taking a strange detour of everyone trying to proxy everyone else's APIs and do manual API Key juggling because platforms aren't running their own MCP servers and clients don't support the latest OAuth changes.

In a year from now, Github will run a single public Github MCP server that you will connect to via OAuth - you won't need to install it locally or faff around with tokens or environment variables at all.
