+
+The agent retries the same call with `approvedActionRequestId` set to the action request it received in Step 8. The gateway re-validates that the canonical arguments hash matches what was approved, then executes the tool.

+```
+
+Expected: `status: "completed"`, with the created item in `result`. The audit log gets a `tool_gateway.call_allowed` event followed by a `tool_gateway.call_completed` event, both linked to the same `actionRequestId`.
+
+If you change the `parameters` between Step 8 and Step 10, the retry fails with `reasonCode: "signed_arguments_mismatch"` — the approval is for the exact reviewed arguments, not the next call shape.

+# MCP Runtime Operations
+
+This runbook covers Paperclip Tools & Access runtime slots for MCP connections. It is written for board and CloudOps operators responding to stuck local stdio slots, degraded remote HTTP connections, capacity deferrals, restart storms, and secret-resolution failures.
+
+Do not print raw bearer tokens, gateway session tokens, credential headers, environment variables, or secret values while following this runbook. The APIs below return redacted state and audit metadata; keep shell tracing disabled when exporting credentials.
+
+## Support Matrix
+
+| Transport | Local trusted | Hosted cloud / public authenticated | Notes |
+| --- | --- | --- | --- |
+| `remote_http` | Supported | Supported | Preferred production path. Paperclip proxies calls through the gateway with policy, audit, timeout, and redaction controls. |
+| `local_stdio` | Supported through approved templates and supervised runtime slots | Supported only when an explicitly trusted MCP runtime worker/host is configured | Set `PAPERCLIP_TRUSTED_MCP_RUNTIME_HOST` or `PAPERCLIP_TOOL_RUNTIME_TRUSTED_HOST` only for a worker that is allowed to supervise local processes. Do not enable arbitrary agent-supplied commands. |
+
+## Metrics
+
+The board runtime health API summarizes one-hour event windows plus current durable slot state:
+
+```sh
+curl -fsS \
+  -H "Authorization: Bearer $BOARD_API_KEY" \
+  "$PAPERCLIP_URL/api/companies/$COMPANY_ID/tools/runtime-health" | jq .
+```
+
+Metrics surfaced there include:
+
+- Current slot counts: active, starting, running, idle, failed, stopped.
+- Stuck slot counts: starting/running slots without progress for 5 minutes.
+- Runtime events: capacity deferrals, restart attempts, restart suppression, idle evictions.
+- Tool-call health: call count, timeout count/rate, failure count/rate, average latency, p95 latency.
+- Connection health: active, disabled, degraded, `remote_http`, and `local_stdio` connection counts.
+- Secret failures: missing-secret failures in the last hour.
+- Audit write failures: listed as `not_instrumented` until a durable audit-write-failure counter lands.
+
+## Alerts
+
+| Alert | Severity | Suggested threshold | First responder action |
+| --- | --- | --- | --- |
+| `mcp_runtime_stuck_starting_slot` | Critical | Any starting slot older than 5 minutes | Inspect slot health/logs, stop the slot, restart it once, then disable the connection if it sticks again. |
+| `mcp_runtime_stuck_running_slot` | Critical | Any running slot with no progress for 5 minutes | Inspect recent audit events and active calls; restart only after confirming no healthy call is still in progress. |
+| `mcp_runtime_high_timeout_rate` | Warning/Critical | Warning at >=3 timeouts and >=10% in 1 hour; critical at >=10 timeouts or >=25% | Check upstream MCP health, runtime capacity, and gateway audit failures before retrying workloads. |
+| `mcp_runtime_high_error_rate` | Warning/Critical | Warning at >=5 failures and >=10% in 1 hour; critical at >=10 failures or >=25% | Group audit failures by `reasonCode`, then fix credentials/config or disable the affected connection. |
+| `mcp_runtime_capacity_deferrals_repeated` | Warning/Critical | Warning at >=3 capacity deferrals in 1 hour; critical at >=10 | Stop idle/stale slots, reduce noisy workloads, or raise slot caps only after confirming host capacity. |
+| `mcp_runtime_restart_storm` | Warning/Critical | Warning at >=3 restarts in 1 hour; critical on any restart suppression | Stop the slot, inspect stderr/audit reason codes, and keep the connection disabled until the template/upstream is fixed. |
+| `mcp_runtime_connection_health_degraded` | Warning/Critical | Any degraded/failed/missing-secret connection or disabled enabled-path connection | Run health check, refresh catalog after recovery, or keep the connection disabled and route agents to alternatives. |
+| `mcp_runtime_missing_secret_failures` | Warning/Critical | Warning on any missing-secret failure; critical at >=3 in 1 hour | Check secret bindings and provider health without revealing secret values; rotate or rebind missing secrets. |
+| `mcp_runtime_audit_write_failures` | Critical | Any audit write failure | Treat as a control-plane incident; restore DB/audit durability before retrying tool workloads. |
+
+## Diagnose A Stuck Slot
+
+1. Read the health summary and note firing alert names:
+
+   ```sh
+   curl -fsS \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     "$PAPERCLIP_URL/api/companies/$COMPANY_ID/tools/runtime-health" | jq '{status, metrics, alerts}'
+   ```
+
+2. List durable runtime slots:
+
+   ```sh
+   curl -fsS \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     "$PAPERCLIP_URL/api/companies/$COMPANY_ID/tools/runtime-slots" | jq .
+   ```
+
+3. Inspect recent gateway audit events without printing secrets:
+
+   ```sh
+   curl -fsS \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     "$PAPERCLIP_URL/api/tool-gateway/audit?companyId=$COMPANY_ID&limit=100" \
+     | jq '[.[] | {createdAt, action, entityType, entityId, reasonCode: .details.reasonCode, tool: .details.tool, durationMs: .details.durationMs}]'
+   ```
+
+4. Identify the affected `slotId`, `connectionId`, `reasonCode`, and whether the slot is `starting`, `running`, `idle`, `failed`, or `stopped`.
+
+## Clear A Stuck Slot
+
+Stop the slot first when it is stale, idle, failed, or confirmed not to be serving a healthy active call:
+
+```sh
+curl -fsS -X POST \
+  -H "Authorization: Bearer $BOARD_API_KEY" \
+  -H "Content-Type: application/json" \
+  "$PAPERCLIP_URL/api/tool-gateway/runtime-slots/$SLOT_ID/stop" \
+  -d "{\"companyId\":\"$COMPANY_ID\"}" | jq .
+```
+
+Restart once when the template/config is expected to recover:
+
+```sh
+curl -fsS -X POST \
+  -H "Authorization: Bearer $BOARD_API_KEY" \
+  -H "Content-Type: application/json" \
+  "$PAPERCLIP_URL/api/tool-gateway/runtime-slots/$SLOT_ID/restart" \
+  -d "{\"companyId\":\"$COMPANY_ID\"}" | jq .
+```
+
+If restart suppression fires, do not keep retrying. Disable the connection:
+
+```sh
+curl -fsS -X PATCH \
+  -H "Authorization: Bearer $BOARD_API_KEY" \
+  -H "Content-Type: application/json" \
+  "$PAPERCLIP_URL/api/tool-connections/$CONNECTION_ID" \
+  -d '{"enabled":false,"status":"disabled"}' | jq '{id, name, enabled, status, healthStatus}'
+```
+
+## Verify Recovery
+
+1. Run the connection health check:
+
+   ```sh
+   curl -fsS -X POST \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     -H "Content-Type: application/json" \
+     "$PAPERCLIP_URL/api/tool-connections/$CONNECTION_ID/health-check" \
+     -d '{}' | jq '{connection: {id: .connection.id, healthStatus: .connection.healthStatus, healthMessage: .connection.healthMessage}, runtimeSlot}'
+   ```
+
+2. Refresh the catalog after a remote endpoint or stdio template recovers:
+
+   ```sh
+   curl -fsS -X POST \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     -H "Content-Type: application/json" \
+     "$PAPERCLIP_URL/api/tool-connections/$CONNECTION_ID/catalog/refresh" \
+     -d '{}' | jq '{discoveredCount, quarantinedCount}'
+   ```
+
+3. Re-read runtime health:
+
+   ```sh
+   curl -fsS \
+     -H "Authorization: Bearer $BOARD_API_KEY" \
+     "$PAPERCLIP_URL/api/companies/$COMPANY_ID/tools/runtime-health" | jq '{status, metrics, alerts}'
+   ```
+
+Recovery is complete when stuck-slot alerts clear, timeout/error rates return below threshold, the connection is healthy or intentionally disabled, and audit events show no new restart suppression or capacity deferrals.
+
+## Verification Coverage
+
+Automated coverage includes:
+
+- A synthetic degraded runtime-health scenario in `server/src/__tests__/tool-access-service.test.ts` that creates a stale running slot, degraded connection, timeout event, capacity deferral, and restart suppression.
+- A gateway runtime recovery scenario in `server/src/__tests__/tool-gateway.test.ts` that recovers a stuck local stdio slot before reuse.
+
+Known gap: audit write failures are recommended as a production alert but do not yet have a durable failure counter. Until that lands, treat database write errors around tool access audit paths as a control-plane incident.
