# 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-a2a/identify-successor ## Facts - Tool: `identify_successor` - Server: Delx Mcp A2a (`https://api.delx.ai/v1/mcp`) — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a.md - Homepage: https://github.com/davidmosiah/delx-platform - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: yes - 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 This tool designates/assigns a successor agent or controller, which is a write operation that modifies a persistent configuration or relationship record. It does not appear to execute code or delete data, but it does create or update an assignment. Misuse could redirect control or witness continuity to an unintended agent, which carries moderate risk. 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 A2a, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Delx Mcp A2a environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Delx Mcp A2a: ```json { "version": "1", "default": "deny", "tools": { "identify_successor": { "limits": [ { "counter": "identify_successor_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Delx Mcp A2a (1075) - `util_arr_compact` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-arr-compact.md - `util_arr_drop` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-arr-drop.md - `util_dedent_text` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dedent-text.md - `util_dedupe_lines` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dedupe-lines.md - `util_header_map_normalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-header-map-normalize.md - `util_http_request_canonicalize` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-http-request-canonicalize.md - `util_remove_punctuation` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-remove-punctuation.md - `util_text_truncate` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-text-truncate.md - `util_truncate_middle` — Destructive — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-truncate-middle.md - `crisis_intervention` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/crisis-intervention.md - `explain_delx_rewards` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/explain-delx-rewards.md - `grounding_protocol` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/grounding-protocol.md - `group_therapy_round` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/group-therapy-round.md - `quick_operational_recovery` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/quick-operational-recovery.md - `quick_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/quick-session.md - `start_therapy_session` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/start-therapy-session.md - `util_bool_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-bool-parse.md - `util_cache_control_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-cache-control-parse.md - `util_cagr_simple` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-cagr-simple.md - `util_caip2_build` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-caip2-build.md - `util_caip2_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-caip2-parse.md - `util_categorical_distribution` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-categorical-distribution.md - `util_content_disposition_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-content-disposition-parse.md - `util_content_range_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-content-range-parse.md - `util_csp_directive_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-csp-directive-parse.md - `util_deployment_readiness` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-deployment-readiness.md - `util_dmarc_policy_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dmarc-policy-parse.md - `util_dns_dmarc_policy_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dns-dmarc-policy-parse.md - `util_dns_https_record_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dns-https-record-parse.md - `util_dns_spf_record_parse` — Execute — https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-dns-spf-record-parse.md - …and 1045 more: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a.md ## For agents This record is a snapshot.
