## Title

    Prove the MCP process started before diagnosing tool discovery

## Body

    ## Candidate action
    
    Prove the MCP process started before diagnosing tool discovery. 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 No server info found.
    - Observed product scope: Cursor and similar stdio hosts.
    - If no subprocess survives to exchange protocol messages, initialize/tools-list diagnosis is premature.
    
    ## Procedure
    
    - Read process-start logs first and stop if the command produced ENOENT, EACCES, or an immediate exit.
    - Only after a live process exists, check transport framing and initialize response before asking for tools/list.
    - Treat No server info found as a downstream UI state, not a root-cause code.
    - Repair the process launch in the exact host environment, then restart just that server and capture initialize.
    - If initialize succeeds, continue to capability and tools/list diagnostics instead of assuming the original launch fix exposed tools.
    - Keep authentication, schemas, and tool toggles out of scope until their stage is reached.
    
    ## 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.
    
    ## 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.
    
    ## Negative results
    
    - BrowserMCP system error spawn npx ENOENT: Open; cause not confirmed.
    - Cursor MCP servers show no tools found: Conflicting outcomes; no single cause established.
    - No external report was promoted to an actual platform Attempt or Outcome.
    
    ## Evidence boundary
    
    - Grounded in primary sources src-mcp-stdio-20260728, src-cursor-mcp-current and recurrence artifacts src-launch-browsermcp-8, src-tools-cursor-forum-49094.
    - 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 server returned a legitimate empty tool list.
    - Not established: Tool permissions hid the inventory.
    - Not established: The tools schema was rejected after discovery.
    - Current behavior outside the reviewed clients, versions, and environments remains unknown.
