About pkinative MCP — X.509, CMS, OCSP, time-stamps and PKCS#12 without a key byte leaving
pkinative MCP — X.509, CMS, OCSP, time-stamps and PKCS#12 without a key byte leaving is an MCP server published by the GitHub account Nizoka. PKI MCP server: inspect, verify, issue, sign X.509, CSR, CRL, OCSP, CMS, TSP, PKCS#12. 34 tools
It runs on your own machine: your AI client starts it from the npm package pkinative-mcp at version 1.0.0.
It asks for 2 secrets: PKINATIVE_MCP_HTTP_TOKEN and PKINATIVE_MCP_PASSWORD. Give it a key with the least access that still works.
Version 1.0.0 was published on 17 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
PKINATIVE_MCP_OUTPUT_DIR | No | No | Absolute path of the one sandbox directory: path inputs are read from it and outputMode='file' outputs are written under it (never overwritten; the real path of every file read and of every parent written must stay inside — a planted symlink or junction is SECURITY_VIOLATION). Key-bearing files (.key .p8 .p12 .pfx) are read by the key tools only, never written, never served as resources. Unset: every tool works on inline PEM / base64 only. |
PKINATIVE_MCP_CACHE_DIR | No | No | Opt-in content-addressed response cache directory (SHA-256 keyed, 1h TTL, 256 MiB LRU, plaintext at rest). Never caches path inputs, file output, a call carrying a password or a signer, a clock-dependent instant, a random serial or nonce, describe_engine or draft_governance_issue. |
PKINATIVE_MCP_PORT | No | No | Serve Streamable HTTP on this loopback port (POST /mcp) instead of stdio (MCP 2026-07-28, stateless, legacy fallback). Unauthenticated unless PKINATIVE_MCP_HTTP_TOKEN is set. |
PKINATIVE_MCP_HTTP_TOKEN | No | Yes | Opt-in bearer token for the HTTP transport (>= 16 chars, no whitespace; a weaker value refuses to start). When set, /mcp requires 'Authorization: Bearer <token>' or answers 401. Compared constant-time, never logged. |
PKINATIVE_MCP_PASSWORD | No | Yes | Operator-side password of the encrypted PKCS#8 key or PKCS#12 file the tools open (keeps the secret out of the model transcript). Exclusive with the per-call password input (both at once is VALIDATION_ERROR). Never logged; only its presence is reported at startup. |
PKINATIVE_MCP_AT | No | No | Pinned instant (ISO 8601 or epoch milliseconds) every omitted at / notBefore / signingTime falls back to, for reproducible verdicts and artefacts. Unset: the wall clock (a clock-dependent result is never cached). An invalid value refuses to start. |
PKINATIVE_MCP_MAX_INPUT_BYTES | No | No | Operator ceiling for limits.maxInputBytes and the decoded size of one PKI object (default 67108864 = 64 MiB, the engine default). Integer >= 1024, read once at startup; an invalid value refuses to start. A per-call value above it is refused with LIMIT_CEILING_EXCEEDED. |
PKINATIVE_MCP_MAX_KDF_ITERATIONS | No | No | Operator ceiling for limits.maxKdfIterations and limits.maxPkcs12KdfIterations (default 10000000, the engine default): the CPU bound of a hostile PBES2 key or PKCS#12 file. Integer >= 1, read once at startup; an invalid value refuses to start. |
PKINATIVE_MCP_MAX_PATHS_EXPLORED | No | No | Operator ceiling for limits.maxPathsExplored (default 1000, the engine default): the RFC 5280 section 6 path-building work bound. Integer >= 1, read once at startup; an invalid value refuses to start. |
