About
One MCP server for the contract-ops suite: all nine local-first CLIs as agent tools.
Security Report
This MCP server provides a well-architected interface to a contract-operations CLI suite with strong security practices. Authentication is not required (appropriate for local CLI wrapping), file operations are properly sandboxed to a base directory, shell injection is prevented through execFile (no shell), and signing operations are effectively human-gated through allowlist validation. Minor code quality issues around error handling and logging do not significantly impact security. Package verification found 1 issue.

contract-ops-mcp
One MCP server for the whole contract-ops CLI suite — wire it up once and an agent (Claude, Cursor, Codex, …) gets all nine local-first CLIs as tools: extract, draft, lint, compare, convert, review, and the template + signed-contract vaults. Signing stays human-gated.
Run this
// e.g. Claude Desktop / Cursor MCP config
{
"mcpServers": {
"contract-ops": { "command": "npx", "args": ["-y", "contract-ops-mcp"] }
}
}
The CLIs themselves must be installed (the server shells out to them). Fastest way to get all nine:
curl -fsSL https://cli.drbaher.com/install.sh | sh # local
# …or run the server + CLIs in one container: ghcr.io/drbaher/contract-ops
Call suite_status any time to see which CLIs are present and how to install any that aren't.
Prefer a ready-made agent? contract-ops-agent is a terminal agent that already wraps this server in an enclosure — the model's only tools are the contract-ops tools, no shell/filesystem/signing by construction. Bring your own model (Claude, OpenAI, or any OpenAI-compatible endpoint):
npm i -g contract-ops-agent.
Tools
Curated, ergonomic tools (typed inputs, JSON out) for the common operations, plus two escape hatches for the long tail:
| Tool | What it does |
|---|---|
extract_contract | Any contract (.md/.txt/.html/.docx/.pdf) → structured JSON (parties, dates, clauses, …) |
lint_contract | Internal-consistency findings (placeholders, broken refs, defined-term/numbering/date defects) |
compare_versions | Clause-aware drift between two versions (exit 0 clean · 2 substantive · 3 cosmetic · 4 moved) |
fill_template | Fill a template's placeholders with typed params (deterministic) |
convert_to_pdf | DOCX → PDF (needs a PDF backend, e.g. LibreOffice) |
review_nda | Score an NDA against a house playbook, with evidence |
template_vault_find / template_vault_get | Search / resolve versioned templates (read-only) |
contract_vault_query / contract_vault_due / contract_vault_risk | Query the signed-contract register; project renewal/notice deadlines; renewal-exposure (read-only) |
verify_signature / verify_receipt / audit_show | Verify a signed PDF / a receipt bundle / walk the audit log (read-only) |
catalog(cli) | Return any CLI's full --catalog json — discover the long tail |
run(cli, args) | Escape hatch: run any suite CLI with raw args (no shell) |
suite_status | Which CLIs are installed (+ versions) and how to install the rest |
The curated set and catalog/run are discovery-driven — they ride the suite's uniform --catalog json contract, so they stay in sync as the CLIs evolve.
Safety
- Signing is human-gated. Only sign-cli's read/verify operations are exposed (
verify_signature,verify_receipt,audit_show) — never request-create or sign. This is enforced: therun/catalogescape hatches reject anysignsubcommand outside a read-only allowlist, so request-create/send/sign/approve can't be reached here. Those stay behind sign-cli's own MCP server with its per-signer approval tokens, so this server can't become an unguarded signing path. - Filesystem lockdown. File-path arguments to the curated tools are confined to
CONTRACT_OPS_MCP_BASE_DIR(default: the working directory). Set it to widen the sandbox. - No shell. CLIs are invoked with
execFile(no shell interpolation).
