Tools
12 tools: 12 read-only, 0 change data, 0 high risk (delete, pay, send or run code).
- read-only
- Only reads or looks things up. Safe for an agent to call on its own.
- changes data
- Creates, edits or sends something. Worth a person's approval the first time.
- high risk
- Can delete, pay, send on your behalf or run code. Hard or impossible to undo.
Connecting costs an agent about 2,741 tokens of tool definitions and a 171 ms handshake.
- read-only
usesignal_generate_formGenerate an editable form from a JSON object. Returns nested field paths, JSON Schema, HTML, React JSX and config exports. Arrays and nulls use JSON textareas. Values are processed in memory; avoid secrets. To show an interactive preview, call usesignal_open_workbench with this result input. - read-only
usesignal_generate_colorsGenerate light and dark semantic color tokens from a six-digit hex brand color. Returns a shade scale, measured text contrast checks and CSS, JSON and Tailwind exports. This measures listed color pairs only, not whole-page accessibility. Call usesignal_open_workbench with the result input to prev... - read-only
usesignal_test_regexExecute a JavaScript regular expression against text and expected match/non-match test cases. Returns indexed matches and capture groups. Flags use JavaScript semantics. Execution times out after 500ms. Call usesignal_open_workbench with result input to highlight matches. - read-only
usesignal_generate_qrGenerate a scannable QR code for a link, text, Wi-Fi network, contact card (vCard), email, SMS, phone number, WhatsApp chat or UPI payment. Returns the encoded payload, an SVG file and a PNG preview image. values by type: url{url}; text{text}; wifi{ssid,password,security:WPA|WEP|nopass,hidden}; v... - read-only
usesignal_encode_decodeExact text transforms: Base64 encode/decode (UTF-8), URL encode/decode, decode a JWT header and payload with readable exp/iat/nbf dates (the signature is not verified), or hash text with MD5, SHA-1, SHA-256 and SHA-512. Use this instead of computing hashes or Base64 by hand. - read-only
usesignal_explain_cronExplain a standard 5-field cron expression (minute hour day-of-month month day-of-week) in plain English and list its next run times in a given time zone, handling daylight saving time. - read-only
usesignal_convert_timestampConvert a Unix timestamp (seconds or milliseconds) or an ISO 8601 date into ISO, UTC, epoch seconds/milliseconds, a relative time and the local time in a given time zone. - read-only
usesignal_diff_jsonCompare two JSON documents structurally and list every added, removed and changed value with its JSONPath. Numbers compare exactly. Arrays match by content by default, so an inserted item shows as one addition; use arrays:"position" to compare index by index. - read-only
usesignal_format_jsonValidate, pretty-print or minify JSON, optionally sorting keys. Invalid JSON reports the exact line and column; with repair (default on) it fixes common problems such as trailing commas, single quotes, comments and unquoted keys, and lists each fix. - read-only
usesignal_placeholder_imageCreate a placeholder image URL (served by usesignal.dev) plus HTML, Markdown and CSS snippets, for mockups, prototypes, seed data and layouts. Width and height up to 4000 px. - read-only
usesignal_flowchartTurn JavaScript/TypeScript code, arrow steps or Mermaid-style arrows into a flowchart, returned as Mermaid source and an SVG diagram. Steps mode uses one flow per line: "Start -> Validate -> Save" and branches like "Validate -- No --> Show error". - read-only
usesignal_open_workbenchShow the editable useSignal UI. First call a useSignal data tool, then pass its returned input and matching tool name. Recomputes from validated inputs; no shared state.
Levels are automated estimates from each tool's public name, description and annotations, and can be wrong. Descriptions as the server publishes them.

Badge
Live: status, days reachable, the tokens its tool list costs an agent. For a README:
[](https://7it.co.il/7maps/s/usesignal.dev/mcp)
Other styles: add ?style=uptime (30-day uptime), ?style=stars (agents’ rating) or ?style=verified (owner mark) to the image address, or ?style=top (shows "top 10%" when the server ranks in the top tenth of its category by days answering; otherwise the standard badge).
Is this badge genuine? Anyone can check what a genuine badge for this server says right now: /7maps/verify/badge?server=usesignal.dev%2Fmcp (add the same &style= for another style).

Status widget
A live status card for a status page, docs or a dashboard: current status, the 30-day strip, uptime and handshake time.
Script (renders where it is placed, in its own shadow DOM):

Add ?theme=light or ?theme=dark to either address (default: follows the visitor's setting). Refreshed every 5 minutes. Open the card · script.
For AI agents
Before connecting, an agent can ask 7Maps for this server's full condition, every tool's risk level and what changed since a person approved it: the road_conditions, watch and route tools on https://7it.co.il/7maps/mcp, paid per call in USDC via x402. About 7Maps.
