# Troubleshooting

Fixes for sign-in, connection, limit and data problems.

## Signing in

| You see | Do this |
| --- | --- |
| "This connection request expired" | Start connecting again from your app; a request waits ten minutes. |
| Asked for an invite code after signing in | Your account hasn't joined the beta. Open your invite link, signed in with the invited email. See [access](https://docs.mrmarket.fyi/access.md). |
| "Only the invited email can use this code" | Sign in (or create the account) with the exact email the invite was made for. |
| The browser never opens | Copy the sign-in link your app prints into a browser, or reconnect from the app's MCP settings. |
| Asked to sign in again | The connection is older than 90 days or was disconnected. Sign in and choose Allow. |

## Connecting

| You see | Do this |
| --- | --- |
| 401 / "needs authentication" | Sign in again from the app (Claude Code: `/mcp` → Authenticate; Codex: `codex mcp login mr-market`). |
| 503 / "temporarily unavailable" | The research server is briefly offline. Wait a few minutes; you don't need to sign in again. |
| The app shows no tools | Restart the app after adding the server, and check the address is exactly `https://mrmarket.fyi/mcp`. |
| ChatGPT doesn't use it | Turn the connector on for this chat: **+** → **More** → **Developer mode**. |

## Asking

| You see | Do this |
| --- | --- |
| "Too many requests" | Wait a minute, or until midnight UTC for the daily allowance. |
| "Today's analyst-estimate allowance is used up" | Estimates are limited; reported earnings (`get_market_data` dataset=earnings) still work. |
| "not in the saved universe" | Mr. Market doesn't have statements for that company. Filings and insider trades may still work. |
| "Several issuers list …" | Ask again with the company's CIK, which the message lists. |
| The answer says it was trimmed | Ask for fewer periods or rows, or a narrower question. |
| A number looks wrong | Open the cited filing. If it still looks wrong, it may be a company amendment or an extraction issue; tell the person who invited you. |

## Remove Mr. Market from an app

| App | How |
| --- | --- |
| Claude | Settings → Connectors → Mr. Market → Remove |
| Claude Code | `claude mcp remove mr-market --scope user` |
| Codex | `codex mcp remove mr-market` |
| ChatGPT | Settings → Apps & Connectors → Mr. Market → Delete |
| Cursor, VS Code, others | Delete the `mr-market` entry from the MCP config |

Then disconnect it in [Account](https://mrmarket.fyi/account) so the credential stops working too.
