Asana MCP Server - TLS Certificate Validation Error

Issue Summary:
Unable to connect to the Asana MCP Server due to TLS certificate mismatch error.

Error Message:
ERR_TLS_CERT_ALTNAME_INVALID

Root Cause:
The MCP server endpoint is presenting a certificate for Facebook domains instead of Asana domains, causing certificate validation to fail.

Investigation Results:

:white_check_mark: DNS resolution works correctly
:white_check_mark: Network connectivity is functional
:cross_mark: TLS certificate is invalid - shows Facebook certificate instead of Asana certificate

Certificate Details:

  • Certificate presented: wildcard Facebook domain
  • Issuer: DigiCert Global G2 TLS RSA SHA256 2020 CA1
  • Server resolves to Facebook/Meta IP range (31.13.88.26)

Configuration:
Using SSE connection type as documented in Claude Code MCP configuration.

Environment:

  • Client: Claude Code CLI v2.1
  • OS: macOS
  • SSL: LibreSSL

Questions:

  1. Is the Asana MCP server publicly available or does it require authentication?
  2. Are there alternative endpoints to use?
  3. Is this service still under development?

Temporary Workaround:
Disabled the MCP server configuration.

Hello!

Thank you for reaching out and providing such a detailed breakdown of the error.

We have an important update that might resolve this for you! We have officially launched our MCP v2 server, which is now Generally Available. You can find the full details in our official announcement here: New v2 MCP Server Now Generally Available

Regarding your specific setup:

  • Deprecation Notice: The V1 Beta MCP server (https://mcp.asana.com/sse) is now deprecated and is scheduled to shut down on May 11, 2026.

  • Next Steps: We recommend migrating to the v2 server as soon as possible. You can find the updated endpoints and technical requirements in our Official Integration Developer Docs.

  • Client Configuration: Since you are using Claude Code, you may find our specific setup guides useful. We have a list of Compatible Asana MCP Clients that includes dedicated guides for Claude, Cursor, VS Code, and several others.

Please let us know if you have any trouble with the v2 configuration or if you continue to see any certificate mismatches after updating your endpoint. We are happy to help!

Best regards,
