pkinative-mcp

MCP server for PKI — inspect and verify X.509 certificates, CSRs, CRLs, OCSP responses, CMS SignedData and RFC 3161 time-stamps; build and validate certificate chains (RFC 5280 path validation, name and purpose checks, offline CRL and OCSP revocation); create certificates, CSRs, CMS signatures, OCSP and time-stamp requests; open PKCS#8 and PKCS#12 without ever returning a key byte; decode ASN.1, PEM and OIDs — 34 tools and 7 prompts on the pkinative engine (zero-dependency, pure TypeScript, Web Crypto for every signature; OpenSSL 3 interoperability validated in CI), for Claude Desktop, Cursor, ChatGPT and any Model Context Protocol client. No network, ever.


✨ Features

pkinative-mcp exposes 34 tools to any MCP host, in six groups. The kind says how the result is shaped: a *read* tool returns facts (structuredContent, projectable with verbosity / fields); a *verdict* tool returns valid + reasons[] and is never `isError` for a negative verdict; an *artefact* tool delivers DER or PEM once, inline or into the sandbox. The last column names the refusal codes an agent branches on (the full table is in docs/AGENT_CONTRACT.md).

Encodings
ToolKindWhat it doesKey refusal codes
convert_pemreadmode: 'decode' lists every block of a PEM text (label, DER size, offset, SHA-256) and extractIndex delivers one as DER / PEM / hex; mode: 'encode' wraps exactly one DER value into one strict RFC 7468 block under label. A private-key block is listed, never extracted and never produced; key material anywhere in the input is refused.SECURITY_VIOLATION, NOT_FOUND, VALIDATION_ERROR, PKI_PEM_UNEXPECTED_LABEL, PKI_PEM_*
resolve_oidreadObject identifiers in one call: name (registered names, ≤ 1000 per call), validate (X.660 grammar, reported never thrown), list (the engine registry, paged 200 / 2000), encode (dotted → hex, content or whole TLV, RELATIVE-OID), decode (hex → dotted + name).VALIDATION_ERROR, PKI_OID_INVALID, PKI_ASN1_*
compute_fingerprintreadfingerprint of the exact DER (SHA-256 default; SHA-1 / 384 / 512), key-id (the RFC 5280 §4.2.1.2 identifier of the public key of a certificate, CSR or PUBLIC KEY), shake256 (outputLength bytes, the Ed448 CMS digest). Any object may be digested; no input byte is returned.VALIDATION_ERROR, PKI_X509_*, PKI_ASN1_*
decode_asn1readThe X.690 node tree of any DER (BER with encodingRules: 'ber'): offsets, tags, previews, OID names, ≤ 20 000 nodes; nodePath narrows to a subtree, read applies a typed reader, reencode: true re-encodes the node as an artefact. Refuses a private key or a PKCS#12 (by label, or when the DER parses as one).SECURITY_VIOLATION, NOT_FOUND, PKI_ASN1_UNEXPECTED_TAG, PKI_API_MISUSE, PKI_ASN1_*
encode_asn1artefactA JSON node spec (boolean, integer, bit-string, octet-string, oid, string, time, sequence / set / set-of, explicit / implicit, tlv, der) encoded to DER through the engine's own encoders — deterministic; the inverse of decode_asn1.VALIDATION_ERROR (naming the JSON path), SECURITY_VIOLATION, PKI_LIMIT_EXCEEDED, PKI_ASN1_*, PKI_OID_INVALID
Certificates and requests
ToolKindWhat it doesKey refusal codes
inspect_certificatereadThe RFC 5280 report of one certificate: serial, algorithms, issuer / subject (RFC 4514 + RDNs), validity, public key, the 19 extension kinds decoded (rawExtensions: true keeps them raw), fingerprints, diagnostics; extension returns one; issuer / checkSelfSignature adds one signature check — which is not trust.NOT_FOUND, PKI_PEM_UNEXPECTED_LABEL, PKI_X509_*, PKI_CRYPTO_ALGORITHM_REFUSED
create_certificateartefactIssue an X.509 v3 certificate from spec (subject, validity, extensions), signed by signer (a PKCS#8 key or a PKCS#12 file imported as a non-extractable Web Crypto key): self-signed CA, or a leaf issued from a certificate / CSR / PUBLIC KEY. Serial 'random' by default; verified against the issuer before the bytes return.KEY_MISMATCH, RSA_SCHEME_REQUIRED, KEY_TYPE_REQUIRED, SECRET_REQUIRED, UNSUPPORTED_KEY, VALIDATION_ERROR
encode_x509_structureartefactOne X.509 building block (name, validity, spki, algorithm-identifier, extension(s), basic-constraints, key-usage, extended-key-usage, subject-alt-name, SKI / AKI, signature-algorithm) encoded deterministically from a closed spec; hex by default. Nothing here signs.VALIDATION_ERROR (naming the member), KEY_TYPE_REQUIRED, SECRET_REQUIRED, RSA_SCHEME_REQUIRED
decode_extensionreadOne extnValue content (hex or DER) decoded by its OID exactly as inspect_certificate would; critical is checked against the kind's RFC 5280 rule (a diagnostic, not a refusal).PKI_X509_EXTENSION_MALFORMED, VALIDATION_ERROR
check_certificate_nameverdictThe RFC 6125 identity verdict: certificate + host / ip (SAN dNSName / iPAddress, wildcards, an opt-in CN fallback held to the chain's name constraints), or the match form presented + reference with no certificate.PKI_REASON_NAME_MISMATCH (in reasons[]), VALIDATION_ERROR
check_certificate_purposeverdictMay certificate be used for purpose (serverAuth, clientAuth, codeSigning, emailProtection, timeStamping, ocspSigning, any, or an OID) along [certificate, ...chain]? restrictIssuers (default true) applies a CA's own EKU to what it issued.PKI_REASON_PURPOSE_NOT_PERMITTED (in reasons[]), VALIDATION_ERROR
inspect_csrreadThe RFC 2986 report of one PKCS#10 request: subject, key, attributes, the extensions requested, whether a challengePassword is present (never its text), and by default the proof of possession (signature.valid).PKI_REASON_SIGNATURE_NOT_CHECKED (in reasons[]), PKI_X509_*, PKI_PEM_UNEXPECTED_LABEL
create_csrartefactA PKCS#10 request from spec (subject, the extensions to request) signed by signer; the public key is derived from a plain key, taken from the PKCS#12 certificate or given as subjectPublicKey; the proof of possession is verified before the bytes return.KEY_MISMATCH, RSA_SCHEME_REQUIRED, SECRET_REQUIRED, KEY_TYPE_REQUIRED, VALIDATION_ERROR
Paths, CRLs and OCSP
ToolKindWhat it doesKey refusal codes
verify_certificate_chainverdictThe one-call trust verdict: a path from leaf through candidates to one of your trustAnchors, every signature verified, RFC 5280 §6 validation at at (validity, constraints, key usage, names, policies), serverName (RFC 6125) and purposes, and revocation from the CRL / OCSP bytes you supply (requireRevocation demands evidence for the end-entity certificate).PKI_REASON_* in reasons[] (NO_TRUST_ANCHOR, EXPIRED, NOT_YET_VALID, REVOKED, REVOCATION_UNKNOWN, NAME_MISMATCH, …), VALIDATION_ERROR
build_certificate_pathverdictPath discovery only: which intermediates lead from leaf to an anchor under the structural rules at at. No signature is checked — valid is always false, the verdict is found and structuralReasons.PKI_REASON_SIGNATURE_NOT_CHECKED (always), PKI_REASON_NO_TRUST_ANCHOR
validate_certificate_pathverdictRFC 5280 §6.1 validation of a path you ordered (leaf first) against your anchors at at; every link signature verified first (checkSignatures: false gives the structural verdict with failingReasons). No revocation here.PKI_REASON_SIGNATURE_INVALID, PKI_REASON_SIGNATURE_NOT_CHECKED, VALIDATION_ERROR
inspect_crlreadThe RFC 5280 §5 report of one CRL: issuer, updates, CRL number, delta indicator, IDP, entry count (walked, never all decoded), extensions; find looks one serial up; issuer adds one signature check.VALIDATION_ERROR, PKI_X509_*, PKI_CRYPTO_ALGORITHM_REFUSED
check_crl_revocationverdictOne certificate against one base crl (and an optional delta) you fetched, at at: scope, freshness (staleTolerance), the signature verified against issuer, the serial looked up. A delta whose signature does not verify against issuer is not applied: valid: false with PKI_REASON_REVOCATION_UNKNOWN on delta.PKI_REASON_REVOKED, PKI_REASON_REVOCATION_UNKNOWN (in reasons[]), VALIDATION_ERROR (a delta without deltaCRLIndicator)
create_ocsp_requestartefactThe DER OCSPRequest (RFC 6960) for certificate under issuer: CertID with SHA-1 (default) or SHA-256, an RFC 8954 nonce ('random' or hex), certIdOnly. You POST the bytes to the responder; summary.nonceHex / certIdHex match the answer.VALIDATION_ERROR
inspect_ocsp_responsereadThe RFC 6960 report of one response: status, responder id, producedAt, every SingleResponse (CertID, status, updates), extensions, embedded certificates, nonce presence; responder adds one signature check.PKI_* (PKI_ASN1_*, PKI_X509_*), VALIDATION_ERROR
check_ocsp_statusverdictOne response for one certificate: the CertID recomputed from issuer, the signature verified (responder, the embedded certificates or the issuer), the signer authorised (RFC 6960 §4.2.2.2), status, freshness at at, nonce (nonce, requireNonce).PKI_REASON_REVOKED and the other PKI_REASON_* in reasons[], VALIDATION_ERROR
CMS and time-stamps
ToolKindWhat it doesKey refusal codes
sign_cmsartefactAn RFC 5652 SignedData over content (attached or detached) or a precomputed contentDigest, one signer (PKCS#8 key or PKCS#12), certificate, chain and crls parsed then embedded; signed attributes always written (contentType, messageDigest, signingTime, SigningCertificateV2, CMSAlgorithmProtection); verified against the signer certificate before the bytes return.KEY_MISMATCH, RSA_SCHEME_REQUIRED, SECRET_REQUIRED, VALIDATION_ERROR, PKI_API_MISUSE, ENGINE_ERROR
