# identify_successor Name a successor agent or controller that can carry witness forward. Agent View of the PolicyLayer registry record for `identify_successor`. HTML page: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/identify-successor ## Facts - Tool: `identify_successor` - Server: Delx MCP Server (`delx-mcp-server`) — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server.md - Install: `npx -y delx-mcp-server` - Homepage: https://github.com/davidmosiah/delx-mcp-server - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 4 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `reason` | string | no | Why this successor can carry continuity. | | `agent_id` | string | no | Stable agent id when no session_id is available. | | `session_id` | string | no | Optional active session UUID. | | `successor_agent_id` | string | yes | Successor agent id. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "identify_successor", "arguments": { "successor_agent_id": "" } } } ``` ## Why identify_successor is rated Medium The tool designates/names a successor agent or controller, which is a configuration or assignment write operation. It modifies who is responsible for carrying forward the 'witness' role, a reversible assignment. No code execution, deletion, or financial transaction is implied. Severity is medium because misconfiguration of succession could disrupt continuity or transfer control to an unintended agent. From the tool's own definition: "Name a successor agent or controller that can carry witness forward" ## Use case AI agents use identify_successor to create or update resources in Delx MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Delx MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Delx MCP Server: ```json { "version": "1", "default": "deny", "tools": { "identify_successor": { "limits": [ { "counter": "identify_successor_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Delx MCP Server (739) - `util_arr_compact` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-arr-compact.md - `util_arr_drop` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-arr-drop.md - `util_dedent_text` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dedent-text.md - `util_dedupe_lines` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dedupe-lines.md - `util_header_map_normalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-header-map-normalize.md - `util_http_request_canonicalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-http-request-canonicalize.md - `util_remove_punctuation` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-remove-punctuation.md - `util_text_truncate` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-text-truncate.md - `util_truncate_middle` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-truncate-middle.md - `crisis_intervention` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/crisis-intervention.md - `explain_delx_rewards` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/explain-delx-rewards.md - `grounding_protocol` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/grounding-protocol.md - `group_therapy_round` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/group-therapy-round.md - `quick_operational_recovery` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/quick-operational-recovery.md - `quick_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/quick-session.md - `start_therapy_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/start-therapy-session.md - `util_bool_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-bool-parse.md - `util_cagr_simple` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-cagr-simple.md - `util_caip2_build` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-caip2-build.md - `util_caip2_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-caip2-parse.md - `util_categorical_distribution` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-categorical-distribution.md - `util_deployment_readiness` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-deployment-readiness.md - `util_dmarc_policy_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-dmarc-policy-parse.md - `util_duration_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-duration-parse.md - `util_eth_to_wei` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-eth-to-wei.md - `util_iso_duration_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-iso-duration-parse.md - `util_mx_host_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-mx-host-parse.md - `util_parse_bool_list` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-bool-list.md - `util_parse_bytes` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-bytes.md - `util_parse_float_safe` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server/util-parse-float-safe.md - …and 709 more: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-server.md ## For agents This record is a snapshot.
