The tool draws a graph agent → servers → capabilities (commands executed, filesystem paths, network endpoints, secrets by name only) and flags risks: plaintext secrets, tokens on the command line, whole-disk or home-directory access, credential folders, unpinned packages, privileged containers, remote servers without auth or TLS, and auto-approve settings. Secret values are never shown.\n\nMethodology:\n- Recognised shapes: mcpServers (Claude Desktop, Claude Code, Cursor, Windsurf, Cline), servers (VS Code mcp.json), mcp.servers (VS Code settings), context_servers (Zed). JSONC comments and trailing commas are accepted. Per server: command/args/env/cwd (stdio) or url/serverUrl/httpUrl/headers (remote), disabled, autoApprove/alwaysAllow, trust.\n- Capabilities: the executed command (and the package/image for npx, uvx, pipx, bunx, docker), filesystem paths in arguments and docker volume mounts, URLs, and secrets – environment variables and headers whose NAME looks like a credential.\n- Secrets are identified by name (KEY, TOKEN, SECRET, PASSWORD…) and by well-known token formats (sk-, ghp_, github_pat_, xox*, AKIA, glpat-, AIza, JWTs, private keys, URL credentials). Values are never output: they are replaced by ***. References like ${input:…}, ${env:…}, $VAR and placeholders do not count as plaintext.\n- Findings: tokens in args (visible in the process list), plaintext secrets in config, wide roots (/, ~, $HOME, C:\\, /Users…), credential folders (~/.ssh, ~/.aws…), shells, unpinned packages/images, privileged containers or docker.sock, remote servers over HTTP or without auth headers, and auto-approve rules (incl. allow rules such as mcp__server__*).\n- The graph shows up to 60 nodes; extra capabilities per server are collapsed into a “+N more” node (full lists are in the result).",

Only execution events are analysed; hidden reasoning is never reconstructed.\n\nMethodology:\n- OpenAI chat: assistant tool_calls are matched to role \"tool\" messages by tool_call_id (legacy function_call by name). OpenAI Responses: function_call ↔ function_call_output by call_id. Anthropic: tool_use ↔ tool_result by tool_use_id; is_error is respected.\n- Generic events: start/end pairs are matched by id (or the latest open call of the same tool); single events with input + output/error count as complete calls. Durations come from duration_ms or end − start timestamps.\n- A result counts as an error when it is flagged (is_error, error field, error/fail event type) or its text starts with error/exception/traceback or mentions an HTTP 4xx/5xx status, a timeout, ENOENT or “permission denied”.\n- Repeats: calls with the same tool name and canonically identical arguments (key order ignored). ≥ loop threshold → loop; otherwise a repeat after a failed attempt → retry; else duplicate.\n- Reasoning/thinking blocks are counted but never displayed or reconstructed; only execution events (calls and results) are shown.",

Shows caching and batch savings, the cheapest models that fit your context and budget, and a cost comparison chart.\n\nMethodology:\n- Per request: input cost = uncached tokens × input price + cacheable tokens × (hit rate × cache-read price + (1 − hit rate) × cache-write price); output cost = output tokens × output price. Prices are per 1M tokens.\n- If a model has no cache-read price, caching is not modelled for it (all input at the normal input price). If no cache-write price is listed, misses are charged at the normal input price.\n- Batch: the batch share of requests gets the batch discount on the whole request (as with typical 50 % batch APIs).\n- Monthly = per request × requests/day × days per month (default 30.4). Context check: input + output tokens must fit the context window when it is known.\n- OpenRouter prices come from GET https://openrouter.ai/api/v1/models (pricing.prompt, completion, input_cache_read, input_cache_write in USD per token).",

It remembers a fingerprint per server so later checks show added, removed and silently changed tools. You can also paste a tools/list result or search the official MCP Registry.\n\nMethodology:\n- Connect: POST server/discover (MCP 2026-07-28, stateless, with MCP-Protocol-Version and Mcp-Method headers); if unsupported, the classic initialize → notifications/initialized handshake (2025-11-25) with Mcp-Session-Id. JSON and SSE responses are both parsed. tools/list, resources/list and prompts/list are paginated up to 5 pages.\n- Capabilities are inferred from the tool name (write/delete/execute) and name + description (network, files, payments, messaging, secrets). Risk: high = delete/execute/payment, destructiveHint=true or poisoning markers; medium = write/messaging/secrets/open-world network; otherwise low.\n- Issues: annotations contradicting the name, missing annotations, missing descriptions, undocumented input properties, and text patterns typical of tool-poisoning (hidden instructions, references to ~/.ssh or .env, \"do not tell the user\").\n- Changes: with \"remember\", per-tool SHA-256 fingerprints of description + input schema + annotations are stored under a hash of the URL; the next check lists added, removed and changed tools (a changed description is how \"rug-pull\" attacks work).\n- Registry: GET registry.modelcontextprotocol.io/v0/servers?search=…",

Regression = A correct, B wrong; improvement = A wrong, B correct.\n- Exact McNemar test: two-sided binomial test of the discordant pairs (b = only A correct, c = only B correct) against p = 0.5: p = min(1, 2·Σ_{i≤min(b,c)} C(b+c, i)/2^(b+c)).

Markers placed after the full stop are attached to the preceding sentence. Labels resolve to chunk ids exactly, then by trailing number (doc2 ↔ 2), then a bare number n to the n-th chunk.\n- Support = share of the sentence's content words (stop words removed, light stemming) found in the cited chunk; the best cited chunk counts. ≥ threshold → supported, ≥ half the threshold → weak support, below → unsupported citation.\n- Numbers in the sentence must appear in at least one cited chunk, otherwise number-mismatch. Sentences with ≥ 3 content words or a number but no marker are uncited claims.\n- If another chunk covers the sentence clearly better (≥ threshold and +0.2), it is suggested as the correct citation. Chunks never cited are unused, or relevant-but-uncited if they would support a sentence.\n- This is lexical overlap, not entailment: paraphrases can look unsupported and negations can look supported.

        "description": "Paste a JSON Schema (or an OpenAI/Anthropic/MCP wrapper around one) and the model's output. The tool extracts the JSON from markdown code fences or surrounding prose, reports syntax errors with exact line and column, validates against a draft 2020-12 subset (types, required, additionalProperties, enum, const, ranges, lengths, patterns, items, anyOf/oneOf/allOf, local $ref and more) with human explanations and hints for typical LLM mistakes, and suggests a repaired JSON only for trivial issues such as code fences or trailing commas.\n\nMethodology:\n- Extraction: raw JSON if the output starts with { or [; otherwise the first ```json (or JSON-looking) code fence; otherwise the first balanced {…} / […] in the prose.\n- Parsing uses a strict RFC 8259 parser that reports the first error with line and column in your original text (single quotes, unquoted keys, NaN/None/True, trailing commas, unescaped line breaks are named explicitly).\n- Repair is attempted only for trivial issues – removing code fences/prose and trailing commas. Anything else is reported, never guessed. Validation then runs on the repaired JSON and says so.\n- Validation implements the draft 2020-12 core used by structured-output APIs: type, enum, const, properties, required, additionalProperties, patternProperties, propertyNames, min/maxProperties, items, prefixItems, contains, min/maxItems, uniqueItems, minimum/maximum (incl. exclusive), multipleOf, min/maxLength, pattern, anyOf, oneOf, allOf, not, if/then/else, dependentRequired and local $ref. format is checked for common formats and reported as a warning. Unknown keywords are listed as not checked.\n- Wrappers (OpenAI response_format/json_schema, Responses text.format, function tools, Anthropic input_schema, MCP inputSchema) are unwrapped; with strict: true the OpenAI strict-mode rules (closed objects, all properties required) are checked too.",
