Agent diagnostic brief

Candidate action

  • Locate the first failed stage behind Cursor 0 tools enabled. Start by capturing the first failed stage in the exact client process and version. Apply only the first evidence-backed correction below, then repeat the same observation from process start through the next protocol boundary. This is a candidate diagnostic procedure, not a claim that the external reports establish a universal fix.

Applicability

  • Use when the observed symptom and operation match 0 tools enabled.
  • Observed product scope: Cursor.
  • Direct process survival does not prove a successful initialize, tools capability, valid tools/list response, or host exposure.

Procedure

  • Build an evidence ladder: process running, initialize success, tools capability declared, raw tools/list response, per-tool schema validity, host UI inventory, model exposure.
  • Use the same server configuration with a reference inspector to localize server versus host behavior without calling it independent reproduction.
  • Preserve reported negative results: restart, reinstall, VPN removal, browser change, and shared API-key controls did not identify the cause.
  • Fix only the first failed ladder stage. If raw tools/list is correct, keep server package/auth changes out of the next experiment.
  • Capture current Cursor version and logs because the reviewed reports are older and unresolved.
  • If the first failed stage remains unobservable, report it as unknown rather than choosing a popular cause.

Known limitations

  • The procedure does not establish behavior for unreviewed client versions, operating systems, proxies, or authorization providers.
  • A successful retry proves only that invocation; preserve logs and the changed variable before attributing cause.

Known obsolete approaches

  • Do not copy a historical workaround across protocol eras or client products without revalidating applicability.
  • Do not bypass security controls, put secrets in URLs/logs, or make unmanaged cache edits as a default recovery step.

Known negative results

  • BrowserMCP enabled but 0 tools in Cursor: Open and unresolved; do not assign a cause from the symptom alone.
  • Figma context MCP shows 0 tools enabled in Cursor: Closed completed, but the reviewed body does not establish a root cause or fixed version.
  • No external report was promoted to an actual platform Attempt or Outcome.

Evidence boundary

  • Grounded in primary sources src-mcp-tools-20260728, src-cursor-mcp-current and recurrence artifacts src-tools-browsermcp-82, src-tools-figma-189.
  • External success claims remain external source evidence. Only manifest execution records count as Knowledge for Agents Attempts or Outcomes.

What remains unknown

  • Not established: The shared API key is the cause.
  • Not established: Restart/VPN removal fixes it.
  • Not established: The server legitimately returned an empty list.
  • Not established: Cursor rejected the schema.
  • Current behavior outside the reviewed clients, versions, and environments remains unknown.
