Install

Works with Claude Code, Codex, VS Code, Cursor, Windsurf, Claude Desktop. Read the repository before you give any tool access to your data.

npx agentmarket install connector/kinbinghua-lgtm-agent-core-mcp

Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

Tools (15)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • base_convertread-only

    Convert an integer string between bases 2 and 36 with arbitrary precision. Uses big-integer parsing, so values beyond IEEE-754 double precision (2^53) stay exact, which is exactly where naive conversion goes wrong. A leading 0b/0x/0o prefix is ignored.

  • convertread-only

    Description is built at runtime.

  • date_addread-only

    Offset an ISO-8601 date by days, weeks, months, years, hours, minutes or seconds. Negative amounts subtract. Calendar-correct across month ends and leap years.

  • date_calcread-only

    Interval between two ISO-8601 dates in days, weeks, months, years, hours, minutes, seconds or businessDays (Mon-Fri). Months and years use true calendar arithmetic, not 30/365-day approximations. All math is UTC.

  • diff_textread-only

    Compute an exact line-by-line diff between two texts using a longest-common-subsequence algorithm. Returns per-line operations (equal/del/ins) with line numbers plus added/removed/unchanged counts. Exact and reproducible; refuses oversized input rather than hanging.

  • fuzzy_matchread-only

    Score every candidate string against a query using the Sorensen-Dice coefficient over character bigrams and return the best matches in descending order. Deterministic. Useful for deduplication, record linkage, typo-tolerant lookup and confirming which of several candidates was meant.

  • hashread-only

    Compute a cryptographic hash of a UTF-8 string. Returns hex and base64 digests plus the UTF-8 byte length. Supports sha256 (default), sha512, sha1, md5, and HMAC variants via hmacKey. Use for content fingerprints, deduplication and integrity checks.

  • json_pickread-only

    Resolve several paths against one JSON document in a single call. Cheaper than issuing many json_query calls when you need multiple fields.

  • json_queryread-only

    Extract a value from a JSON document by path, e.g. "a.b[0].c" or "$.items[3].name". Reports `resolved` (did the path reach a location) separately from `found` (is the value non-null), so absent is distinguishable from present-but-null. Failure types are specific: missing-key, out-of-range, not-an-array, not-an-object.

  • json_validateread-only

    Check whether a string is valid JSON. On failure returns the parser message plus the computed line and column of the error. On success returns the top-level shape. Distinguishes valid-but-empty-object from invalid.

  • parse_tableread-only

    Parse delimited text into a header plus rows, handling quoted fields, escaped quotes, embedded delimiters and embedded newlines (RFC 4180 style). If no delimiter is given, the most frequent candidate on the first line is chosen and reported back. Use instead of splitting on commas, which breaks on any real CSV.

  • regex_analyzeread-only

    Statically analyse a regular expression for catastrophic backtracking (ReDoS): nested quantifiers, overlapping alternation inside repeated groups, backreferences under quantifiers, excessive wildcards. Returns a risk level and the specific reasons. The pattern is not executed.

  • regex_extractread-only

    Apply a regular expression and return every match with its index, numbered capture groups and named groups. Iteration and match counts are hard-capped so a pathological pattern cannot hang the host. The response includes a ReDoS risk assessment of the pattern.

  • similarityread-only

    Sorensen-Dice similarity of two strings, from 0 (no shared character bigrams) to 1 (identical). One deterministic comparison.

  • text_statsread-only

    Exact text statistics: Unicode code points, UTF-8 bytes, lines, non-empty lines, words, sentences, paragraphs, unique words, average word length and most frequent words. Word segmentation is Unicode-aware so non-Latin scripts are counted correctly. Use whenever a count must be exact.

Done for you

Rather not set it up yourself?

Chalk Labs scopes, builds and runs agents for your team: the task audit, the eval harness, the integrations and the weekly ops report. Fixed scope, priced before we start.
