connect-context-dev

A setup and troubleshooting guide for connecting Cursor to Context.dev, a service that provides website and web-search tools through an MCP server.

In plain words
What is it for?
Use it to connect Context.dev with OAuth, verify the connection, and fix common setup problems.
Why use it?
It removes confusion around enabling the server, signing in, and diagnosing missing tools or authentication errors.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

connect-context-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Connect Context.dev in Cursor

Standard connection

  1. Open Cursor Settings → Tools & MCP.
  2. Find the context server installed by this plugin and enable it.
  3. Select Connect or Authenticate.
  4. Complete the Context.dev sign-in and consent flow in the browser.
  5. Return to Cursor and confirm that the server lists its tools.

The plugin uses the production Streamable HTTP endpoint at https://mcp.context.dev/mcp. OAuth is discovered from the server automatically. Do not add headers, client secrets, or API keys to mcp.json.

Verify

Use a read-only request:

Use Context.dev to scrape https://www.context.dev and return the page title.

The agent should call web-scrape-markdown. A successful tool call confirms both the MCP connection and the authenticated Context account.

Troubleshooting

Symptom Action
context is missing Refresh or reinstall the plugin, then reload the Cursor window
A second legacy Context.dev server appears Remove the old manual server and reinstall this plugin
401 or authentication required Disconnect the server, reconnect it, and complete OAuth again
Browser flow does not open Open the server details and select Authenticate manually
Tools remain unavailable after OAuth Reload the Cursor window and re-enable the server
Account has insufficient credits Review usage in the Context.dev dashboard; do not repeatedly retry

Never ask the user to paste an OAuth token or private API key into chat.

Direct API development

OAuth covers Cursor's MCP connection. A user only needs an API key when writing their own application against the Context.dev REST API or SDK. In that case, direct them to the Context.dev dashboard and store the key in a server-side CONTEXT_DEV_API_KEY environment variable. Do not place it in this plugin's MCP configuration.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
