MCP dropped its execute sandbox: every API operation an agent may call is now its own tool, named by its operationId. The docs still taught execute, tools.search, and tools.describe. That text reached docs/llms.txt ("five tools, execute sandbox") and about 40 places in llms-full.txt.

What changed

• agents/mcp-server, rewritten for the current surface:
  • Operation tools, plus the product tools that sit on top of them (publish, operation_status, the show_space_* views, show_domains, choose_space, resume_execution, cli_login).
  • The current default OAuth scopes, including spaces:access.write, versions:download, teams:members.write, and sell:write. spaces:delete is opt-in.
  • uploadId publishing and the url input on operation_status.
  • Approvals: an approval card or approvalUrl, a 24-hour wait, and local action/content.
  • Finding docs through searchDocs and getDocsPage.
  • Removed: the sandbox section and its JavaScript examples.
• agents/index, agents/skills, cli/agents: the tool overview, the skill's trigger text and routing table, and the sync-check description now match the current skill and server.
• Client setup pages (Claude Code, Codex, Cursor, other clients): "verify through execute" becomes "call searchDocs". The rollback and access-change notes now name the operations they call.

Changelog entries that mention execute stay as they are; they're history.

Verification

bun run check, validate, build, test:docs (28 pass), verify:routes, verify:public-safety, and Vale on the changed pages (0 alerts). The rebuilt dist/llms.txt now describes the MCP server page as "call any API operation as a tool, and approve sensitive writes". After this merges, the www docs pin needs a bump to publish it.

Summary by CodeRabbit

• Documentation
  • Updated agent setup and verification guidance to use direct documentation search and operation-specific tools.
  • Clarified the available MCP tools, including Space views, publishing, operation status, and resuming paused calls.
  • Expanded guidance on publishing options, access scopes, approvals, and approval time limits.
  • Clarified how to check tool inputs and that structured results are limited to 24,000 characters.

Issues

1 potential issue found:

• The execute-limits eval in evals.yaml still asks about the MCP execute sandbox limits (30 seconds, 64 MiB, no fetch), which this PR removes from /agents/mcp-server. The next eval run will fail or reward stale answers; it isn't covered by test:docs.

Walkthrough

The agent documentation now describes MCP API operations as direct tools instead of operations invoked through execute. It updates tool scopes, publishing and polling inputs, approval behavior, Space views, and agent instructions.

Changes: Direct MCP Tool Documentation

Layer / File(s)	Summary
Runtime, scopes, and tool catalog content/agents/mcp-server.mdx, content/agents/index.mdx	The MCP reference describes operation-specific tools, runtime differences, scopes, on-demand tool loading, and the 24,000-character result cap. The agent index reflects the updated tool catalog.
Operation inputs and results content/agents/mcp-server.mdx	The reference documents publish sources and polling handles, operation_status inputs, separate show_space_* tools, and direct documentation tools.
Sensitive-call approvals content/agents/mcp-server.mdx, content/agents/claude-code.mdx, content/agents/codex.mdx	The MCP reference describes approval pauses, decisions, and resumption. Agent guidance links to the approvals documentation.
Agent instructions for direct tools content/agents/claude-code.mdx, content/agents/codex.mdx, content/agents/cursor.mdx, content/agents/other-clients.mdx, content/agents/skills.mdx, content/cli/agents.mdx	Agent instructions replace execute-based operation discovery with direct tool calls and update tool selection guidance. The CLI reference removes its execute sandbox reference.

Qualify all MCP exposure claims.

domains:write can cover domain purchases when enabled, but that scope does not provide a domain-purchase MCP tool. Bound all catalog claims to operations exposed through MCP, and qualify the dashboard claim without removing the scope description.

-The same server ships in two runtimes. Both expose every Spacefast API operation as its own tool. The difference is the filesystem.
