Evaluate an MCP connector before linking your CRM
Assess an MCP marketing connector’s permissions, data exposure, tool behavior and revocation process before allowing access to customer information.
An MCP connector makes tools available to an AI assistant; its presence in a directory does not tell you whether it fits your CRM controls. Procurement should examine the connection’s actual permissions and behavior before introducing customer data. Start with the smallest useful task.
Identify the connection owner
Record who operates the connector, where it runs, which service receives requests and whose credentials authorize access. Ask for a documented list of tools and data flows. A read-only account-summary task should not require broad permission to delete contacts or send messages. MCP authorization guidance supports limiting requested scopes to intended operations. [2]
Inspect the information returned
Use fictional records to check whether a lookup returns only the relevant contact and fields or exposes an entire account database. Tool names should distinguish searching, reading and changing records. Anthropic’s tool-design guidance emphasizes clear purposes and useful, focused responses. [1] Those qualities also make a connector easier for a marketer and administrator to assess.
Test the boundary conditions
Request a record the test user cannot access, then try an ambiguous name shared by two contacts. The expected behavior is enforced access restriction and explicit disambiguation. Confirm that a claimed update matches the actual CRM change. Test with synthetic instructions embedded in a note to check whether retrieved content can improperly influence unrelated actions.
Prove that access can end
Revoke the connection and confirm that subsequent requests fail appropriately. Record token ownership, audit visibility and the procedure for offboarding an employee or agency. Approve only the documented use case and assigned permissions. This review does not certify the entire protocol or vendor; it gives the team evidence about one connection under its own operating conditions.
