Create an API key at finchreach.com/api-keys, connect LinkedIn at finchreach.com/accounts, then add `https://mcp.finchreach.com/mcp` to Replit Agent with the header `Authorization: Bearer lk_…`. Test with a read, and approve the first draft under Approvals.

## What you need

- A Finchreach account (sign in at [finchreach.com](https://finchreach.com/sign-in)) and the LinkedIn account you want Replit Agent to work on.
- Replit Agent (transport and plan requirements aren’t stated. Traffic goes through Replit’s security scanner).
- About five minutes.

## Step 1: Create a Finchreach API key

1. Sign in at finchreach.com and open [API keys](https://finchreach.com/api-keys).
2. Create a key and name it after the tool, for example “Replit Agent”.
3. Copy it right away: it starts with `lk_` and is shown only once.

## Step 2: Connect your LinkedIn account

1. Open [Accounts](https://finchreach.com/accounts) and click to connect LinkedIn.
2. Follow the steps until the account shows as connected.

Approval mode is on by default: nothing the assistant drafts reaches LinkedIn until you approve it.

## Step 3: Add Finchreach to Replit Agent

1. Open the Integrations pane → MCP servers → + Add MCP server.
2. Enter a name and the HTTPS URL `https://mcp.finchreach.com/mcp`.
3. Under Advanced settings add a custom header: `Authorization` = `Bearer lk_YOUR_KEY` (or `X-API-Key` = `lk_YOUR_KEY`).
4. Click Test & save.

Arbitrary custom headers are supported (Replit’s own example is `X-API-Key`, which Finchreach accepts). OAuth with dynamic registration is detected automatically when a server offers it.

Requirements: Transport and plan requirements aren’t stated. Traffic goes through Replit’s security scanner.

## Step 4: Test the connection

In Replit Agent, start with a read. It runs right away and proves the key and the account work:

> Ask your assistant: “List my connected LinkedIn accounts, then summarize my five latest notifications.”

You should see calls to `linkedin_list_accounts` and `linkedin_get_notifications`. Then try a write, which goes to your approval queue instead of LinkedIn:

> Ask your assistant: “Draft a short LinkedIn post saying I’m trying a new AI assistant workflow. Submit it for my approval.”

## Step 5: Approve or reject it in Finchreach

1. Open [Approvals](https://finchreach.com/approvals). The draft is there with its exact text and the account it would go out from.
2. Approve it to publish, or reject it (reject the test post if you don’t want it live).
3. Replit Agent can check the result with `linkedin_get_action`: pending, approved, rejected, executed, failed or expired.

## Troubleshooting

- If Test & save fails, check for a space or line break pasted with the key.
- 401 or “unauthorized”: the key is wrong, revoked or missing its prefix. Finchreach accepts `Authorization: Bearer lk_…` or `X-API-Key: lk_…`; check for a missing `Bearer `, quotes or a trailing space.
- A tool is missing: the key’s permissions don’t include it. Create a key with the permissions you need under [API keys](https://finchreach.com/api-keys).
- “No LinkedIn account”: connect one under [Accounts](https://finchreach.com/accounts), or reconnect it if its session expired.
- A post or message “didn’t go out”: it is probably still waiting under [Approvals](https://finchreach.com/approvals). Writes run only after you approve them.

Still stuck? Compare your setup with [Replit Agent’s documentation](https://docs.replit.com/build/connect-via-mcp), checked on 2026-10-28; client screens change often.

## What to ask Replit Agent next

> Ask your assistant: “Use my LinkedIn profile to fill in the portfolio app you’re building.”

> Ask your assistant: “After the deploy, draft a LinkedIn post with the live link.”

> Ask your assistant: “Read my LinkedIn profile and draft a short bio for the app’s footer.”

## Questions

### I lost my API key. Can I see it again?

No, a key is shown only once. Create a new one under [API keys](https://finchreach.com/api-keys), put it in your config, and revoke the old one.

### Does Replit Agent see my LinkedIn password?

No. Replit Agent only gets your Finchreach API key. Your LinkedIn connection stays in Finchreach, and you can revoke the key at any time without touching LinkedIn.

### Can I use the same key in several tools?

Yes, but one key per tool (for example one named “Replit Agent”) lets you revoke one without breaking the others.

### How do I disconnect Replit Agent?

Revoke its key under [API keys](https://finchreach.com/api-keys); Replit Agent gets a 401 from then on. Then remove the server from its config.
