Hi everyone,

I’m trying to integrate Palantir Foundry MCP as a remote MCP server, with SnapLogic acting as the MCP client.

SnapLogic requires:

  • An HTTP(S) MCP endpoint URL

  • An authentication token (Bearer or similar)

My questions are:

  1. Does Palantir Foundry expose MCP over a public/accessible HTTP URL, similar to other remote MCP servers (for example GitHub MCP)?

  2. If yes, how can we identify the correct MCP endpoint URL (e.g. /mcp, /mcp/stream, etc.)?

  3. What is the recommended authentication mechanism for MCP access (OAuth2, Foundry token, service account token, etc.)?

  4. Are there any network or security prerequisites (allowlists, reverse proxy, gateway configuration) required to access MCP externally?

The goal is to connect Palantir MCP purely via URL + auth token, without deploying any local adapters, so that SnapLogic can consume Palantir tools as a remote MCP server.

Any guidance or official documentation pointers would be really helpful.

Thanks in advance!

Hey, welcome to the community!

You can look into enabling MCP Hub from the Control Panel, and then accessing it via <your_enrollment_prefix>.palantirfoundry.com/workspace/mcp-hub-app.

Not 100% sure on anything specific for SnapLogic, but the generic approach looks good.

Additional MCP docs can be found here. https://www.palantir.com/docs/foundry/palantir-mcp/overview

Happy building!

Hey Kunal, as far as I am aware:
Palantir MCP does not expose a public HTTP endpoint.

It’s designed to run locally via stdio (standard input/output) and connects to Foundry APIs using your token. The architecture is:

[MCP Client] → [Local MCP Server (stdio)] → [Foundry REST APIs (HTTPS)]

To expose any MCP server over HTTP, you need to either:
- Use/build an HTTP adapter (like https://github.com/sparfenyuk/mcp-proxy)
- Wait for vendors to offer hosted versions
