Set up OpenSEO MCP

OpenSEO MCP lets compatible AI clients call OpenSEO tools for keyword research, SERP inspection, domain research, backlink overview, saved keywords, and rank tracking.

The hosted MCP server URL is:

https://app.openseo.so/mcp

The first connection sends you through OpenSEO login. After authorization, your MCP client can call OpenSEO tools with the project context and account scopes you approved.

For the most current setup UI and a copyable endpoint, open AI & MCP in OpenSEO.

Claude Code

Use user scope to make OpenSEO available across projects. Use local scope for the current repository.

After adding the server, approve the OpenSEO login when prompted.

Available tools

OpenSEO MCP exposes tools for SEO research workflows:

• Research keywords with volume, difficulty, and CPC.
• Fetch live Google organic SERP results for keywords.
• List saved keywords from an OpenSEO project.
• Save useful keywords back to OpenSEO.
• Read rank tracker configs and latest keyword positions.
• Summarize a domain's organic footprint.
• Find keywords a domain already ranks for.
• Check backlink and referring-domain overview data.

What to do after setup

Once OpenSEO MCP is connected, set up OpenSEO Agent Skills. MCP gives your agent access to OpenSEO data. Skills are separate SKILL.md files that tell your agent how to use that data for specific SEO jobs.

Start with one focused workflow instead of asking your agent to "do SEO" broadly.

• Use SEO project setup to capture your SEO goals and website context in a local workspace.
• Use SEO coach if you are new to SEO or are not sure which workflow to run first.
• Use keyword research to discover keyword opportunities.
• Use competitive landscape to map a market before choosing competitors or pages.
• Use competitor analysis to study one competitor.
• Use keyword clustering to turn keywords into page groups.
• Use link prospecting to find outreach prospects for a linkable asset.

Troubleshooting

If your client cannot connect, check that the server URL is exactly https://app.openseo.so/mcp.

If authorization fails, disconnect the OpenSEO server in your client, add it again, and repeat the login flow.

If your agent cannot find a project, ask it to list OpenSEO projects first and use the returned project ID in later tool calls.
