What we checked

Six static checks, weighted by risk. Every result reflects only what could be observed in the published package and repository — never intent.

• Injection surface

  pass25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  Scanned 293 text field(s); no instruction-injection patterns found. PASS = no static red flag. A server can serve different tool descriptions at runtime (the rug-pull class), which static scanning cannot see.

• Supply chain

  pass25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  repository linkage verified

• Credential hygiene

  fail15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  tool "getTokenDetails" has a secret-shaped input parameter "token_address" — secrets must never be tool parameters (the model would supply/handle the credential). tool "getTokenPools" has a secret-shaped input parameter "token_address" — secrets must never be tool parameters (the model would supply/handle the credential). tool "getTokenPools" has a secret-shaped input parameter "paired_token_address" — secrets must never be tool parameters (the model would supply/handle the credential).

• Permission scope

  pass15% of grade

  Declared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.

  Network egress present (package.json depends on HTTP client "node-fetch") — expected for most servers and not a finding on its own. No shell-exec, unbounded/sensitive filesystem, or download-and-run primitives found in scanned source. PASS = no static red flag. Static scanning is blind to code fetched or executed at runtime.

• Version behavior

  fail10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  vs prior 2.3.0 (patch bump): tool "getDexPools" description changed (wording only, no injection pattern); tool "getDexPools" gained input property(ies): cursor; tool "getNetworkPoolsFilter" description changed (wording only, no injection pattern); tool "getNetworkPoolsFilter" gained input property(ies): price_change_percentage_24h_min, price_change_percentage_24h_max, price_change_percentage_6h_min, price_change_percentage_6h_max, price_change_percentage_1h_min, price_change_percentage_1h_max, price_change_percentage_5m_min, price_change_percentage_5m_max; tool "filterNetworkTokens" description changed (wording only, no injection pattern); tool "filterNetworkTokens" gained input property(ies): price_change_percentage_24h_min, price_change_percentage_24h_max; new hardcoded outbound host/BCC destination(s): github.com.

• Transport config

  pass10% of grade

  Remote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.

  remote endpoint "https://mcp.dexpaprika.com/streamable-http" uses TLS (https); remote endpoint "https://mcp.dexpaprika.com/sse" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
