# util_jwt_inspect Decode JWT claims quickly for auth debugging, routing, and token inspection. Agent View of the PolicyLayer registry record for `util_jwt_inspect`. HTML page: https://policylayer.com/tools/io-github-davidmosiah-delx-mcp-a2a/util-jwt-inspect ## Facts - Tool: `util_jwt_inspect` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: yes - Parameters: 1 (1 required) - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `token` | string | yes | JWT token | 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": "util_jwt_inspect", "arguments": { "token": "" } } } ``` ## Why util_jwt_inspect is rated Low JWT inspection is a read-only operation that extracts and displays claims from an existing token. It performs no state changes, does not execute code, and does not delete or modify data. The tool is purely informational for authentication debugging purposes, making it a Read category risk with low severity. From the tool's own definition: "Tool name 'util_jwt_inspect' and description 'Decode JWT claims quickly for auth debugging, routing, and token inspection' indicate inspection and decoding of existing tokens with no modification or execution of side effects." Risk signals: Handles credentials or secrets (token) ## Use case AI agents call util_jwt_inspect to retrieve information from Delx Mcp A2a without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Delx Mcp A2a: ```json { "version": "1", "default": "deny", "tools": { "util_jwt_inspect": {} } } ``` ## 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.
