Part of the Contentful GraphQL Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call graphql_query to retrieve information from Contentful GraphQL Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though graphql_query only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the graphql_query tool do? +

IMPORTANT: Before using this tool, you MUST first use graphql_list_content_types and graphql_get_content_type_schema to understand the available content types and their structure. Execute a GraphQL query against the Contentful GraphQL API. This tool allows you to use Contentful's powerful GraphQL interface to retrieve content in a more flexible and efficient way than REST API calls. The space ID and CDA token are automatically retrieved from environment variables.. It is categorised as a Read tool in the Contentful GraphQL Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on graphql_query? +

Add a rule in your Intercept YAML policy under the tools section for graphql_query. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Contentful GraphQL Server MCP server.

What risk level is graphql_query? +

graphql_query is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit graphql_query? +

Yes. Add a rate_limit block to the graphql_query rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block graphql_query completely? +

Set action: deny in the Intercept policy for graphql_query. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides graphql_query? +

graphql_query is provided by the Contentful GraphQL Server MCP server (ivo-toby/contentful-mcp-graphql). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
