Claude Code /mcp sign-in fails: Hydra echoes client_uri: "" and contacts: null, and Claude Code rejects both (anthropics/claude-code#13685, not planned). Add POST /register to the MCP server: forward to the issuer, remove top-level ""/null fields. sean/ory follow-up points registration_endpoint at https://mcp.sean.farm/register.

fix(mcp): proxy dynamic client registration so Claude Code can register ... 50859cce1f

Claude Code's /mcp sign-in fails against Hydra's /oauth2/register:
Hydra answers with client_uri: "" and contacts: null, and Claude
Code's response schema demands a parseable URL or an absent key
(anthropics/claude-code#13685, closed as not-planned; ory/hydra#4044
tracks the server side, also unfixed).

Add POST /register to the MCP server. It forwards the registration to
the issuer and removes each top-level field whose value is "" or
null. The endpoint takes no bearer token: a registering client has no
credentials yet. sean/ory then points the advertised
registration_endpoint at https://mcp.sean.farm/register.
