docs: add fx to MCP server integrations

[ankur-arch]

Summary

Adds an fx section to the MCP server page under Integrating in AI tools, following the format of the existing Claude Code and Gemini CLI sections: install, ~/.fx/mcp.json config, /mcp auth Prisma --open, /mcp list.

fx is Vercel Labs' terminal coding agent. It differs from the other tools in two ways the section calls out: config lives only in ~/.fx/mcp.json (repo-local MCP files are never loaded), and the root key is mcp rather than mcpServers, with "type": "http" required for remote servers.

Tools list refreshed

The page's tool list was stale (ListDatabasesTool, CreateBackupTool, ...). It now matches tools/list from the live server, all 19 names, grouped by area: workspace/databases, connection strings, backups, schema and queries, object store, documentation.

Tested end to end

With fx 0.0.5 and the exact snippet in this PR:

• /mcp auth Prisma --open authenticates with Prisma Console.
• /mcp list reports state=ready auth=authenticated, negotiated Prisma Postgres MCP 1.0.1, 19 tools.
• "Show me a list of all the databases in my workspace" selects list_prisma_postgres_databases, prompts for approval, and returns the workspace's databases.

Prerequisite that already shipped

This initially failed because fx validates the RFC 8414 issuer field strictly and our metadata was wrong. Fixed in prisma/pdp-control-plane#5008, merged and deployed 2026-08-24; re-tested against production afterwards.

Summary by CodeRabbit

• Documentation
  • Expanded Prisma MCP documentation with categorized workspace, database, schema, query, backup, object-store, connection-string, and documentation capabilities.
  • Added setup instructions for fx integration, including installation, configuration, authentication, readiness checks, and approval behavior.
  • Included guidance for accessing fx MCP documentation and updated the Claude Code MCP documentation link.
  • Updated MCP tool names and descriptions for clearer, more consistent access to workspace details, database operations, schema introspection, SQL queries, backups, recovery, and object-store management.

Walkthrough

The MCP tool catalog now uses categorized, documented snake_case names across the site and documentation. The MCP server documentation also adds fx setup, authentication, readiness, approval, and reference instructions.

Changes

MCP tool integration

Layer / File(s)	Summary
Synchronize MCP tool catalog apps/docs/content/docs/ai/tools/mcp-server.mdx, apps/site/src/lib/agent-skills.ts	Updates MCP tool names and descriptions for workspace, database, connection string, backup, schema, query, object-store, and documentation operations. The Claude Code MCP link is also updated.
Document fx MCP setup apps/docs/content/docs/ai/tools/mcp-server.mdx	Adds fx installation, configuration, authentication, readiness, approval, and reference instructions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to aac56

The documentation may present an inconsistent tool list and overstate approval guarantees for database-capable calls, which could mislead users configuring or operating the integration. The PR is mergeable with explicit owner awareness and follow-up to correct those statements.

In `@apps/docs/content/docs/ai/tools/mcp-server.mdx`:
- Around line 20-55: Update the MCP_TOOLS catalog in agent-skills.ts to use the
19 snake_case identifiers documented here, replacing the conflicting PascalCase
names, and align each entry’s description with the corresponding MCP tool
documentation. Preserve the catalog structure while synchronizing all workspace,
database, connection-string, backup, schema, object-store, and documentation
tools.
- Line 374: Update the MCP authorization guidance around the `/mcp list` example
to explain that fx evaluates permission policy before each MCP tool call, so
saved rules, automatic review, or permission modes may resolve calls without
prompting. Clarify that when an approval prompt appears, users should select the
option matching the desired permission scope.
