Use this worksheet to evaluate MCP servers before connecting them to production workflows. The goal is not to find the most feature-rich server; the goal is to choose a server your IT and governance teams can safely operate.
Read this together with Model Context Protocol for Enterprise Teams so architecture and security decisions stay aligned.
How to score
Scoring is deliberately simple so IT and governance can run the worksheet in one working session. A high total score never overrides a red-line failure—broad write scopes and missing audit fields are blockers even when demo latency looks excellent.
- Score each criterion from 1 (poor) to 5 (strong).
- Mark any red-line failures as blockers regardless of total score.
- Keep evidence links (docs, test logs, security notes) in the final column.
MCP server selection worksheet
Work through each row with security and governance first; integration polish matters only after allowlists, auth, and logging fields pass review. Link completed worksheets to your governance RACI so incident response has a named owner when configuration drifts.
| Area | Criterion | Score (1-5) | Red-line failure? | Evidence / notes |
|---|---|---|---|---|
| Security | OAuth/OIDC or equivalent auth support | |||
| Security | Tool-level allowlist and scope controls | |||
| Security | Read/write separation possible | |||
| Security | Prompt-injection sanitization strategy documented | |||
| Governance | Audit log fields include tool, args hash, actor, timestamp | |||
| Governance | Versioning for server config and policy mappings | |||
| Governance | Incident response owner and escalation path defined | |||
| Operations | SLO/SLA expectations documented | |||
| Operations | Rate limits and retry behavior are predictable | |||
| Operations | Monitoring hooks (errors, latency, call volume) available | |||
| Integration | Works with required model/runtime stack | |||
| Integration | Supports required data sources/tools with least privilege | |||
| Cost | Pricing model matches expected call pattern | |||
| Cost | Cost controls or quotas available | |||
| Vendor fit | Maintenance cadence and support maturity |
IT checklist (go/no-go)
Treat unchecked items as deployment blockers for production write scopes. Staging replay drills should produce log rows that match your audit trail schema before pilot traffic touches customer data.
- [ ] Authentication method approved by security team.
- [ ] Least-privilege scopes mapped per workflow ID.
- [ ] Logging fields validated in a staging replay drill.
- [ ] Prompt-injection test cases passed on representative data.
- [ ] Human escalation rules defined for risky write actions.
- [ ] Rollback path tested if server is unavailable or misconfigured.
- [ ] Ownership documented in governance RACI.
Optional weighted model
Weighted scoring helps compare two acceptable candidates when neither triggers a red line. It does not replace red-line checks—security and audit failures remain blockers regardless of total score.
If your team needs weighted scoring, use:
- Security: 35%
- Governance: 25%
- Operations: 20%
- Integration: 15%
- Cost and vendor fit: 5%
Weighted scoring helps compare candidates, but red-line failures still override total score.
Decision log template
Paste the block into your approval ticket so procurement and security can find the same facts six months later. Link the ticket ID from your change log template when MCP scope changes.
Copy this block into your internal approval ticket:
- Selected server:
- Workflows in scope (v1):
- Approved scopes/tools:
- Known constraints:
- Red-line checks passed: Yes / No
- Pilot start date:
- Review date (30-day):
Common mistakes to avoid
These mistakes recur in first MCP rollouts—especially when demos emphasize speed over allowlists. Read them as release blockers, not post-launch cleanup items.
- Selecting a server based only on demo speed.
- Enabling broad write scopes in the first rollout.
- Shipping without replayable audit evidence.
- Ignoring ownership for configuration drift and incidents.
Start with read-only or low-risk use cases, then expand scope only after eval, observability, and governance signals are stable. For security controls after selection, see Securing MCP and Agent Tools.
