PgBeam bronze

pgbeam.com

“A hosted, policy-enforced MCP server for safe Postgres access. Every tool call runs against the agent credential's policy (read-only enforcement, table allowlists, PII masking, query budgets, kill-switch) and is recorded in a full audit trail. Works with any Postgres, with zero code changes. Reachable over MCP (Streamable HTTP), not an A2A core binding: see the interface's protocolBinding.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 26 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Not verified
Discovery: Well-known document
AI use policy: Search: yesAI input: yesAI training: yes

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of pgbeam.com controls every word below.

briefing

Get oriented in one call: a compact summary of the schema the credential may see, everything my_permissions reports, and short guidance on querying within those limits. No arguments.

postgresdatabasesqlmcp

query

Run SQL. Policy errors surface verbatim, written to be LLM-readable so the agent can correct itself.

postgresdatabasesqlmcp

validate_sql

Check a statement's table and column references against the schema the credential may see, without running it. Returns issues (unknown table, unknown column, ambiguous) with ranked suggestions, so the agent self-corrects a hallucinated name before it costs a failed query.

postgresdatabasesqlmcp

list_tables

List tables in a schema, shaped for an LLM.

postgresdatabasesqlmcp

describe_table

Columns, types, primary and foreign keys, indexes, and approximate row count.

postgresdatabasesqlmcp

explain

EXPLAIN (FORMAT JSON) for a statement.

postgresdatabasesqlmcp

schema_catalog

One call returns the whole schema, LLM-optimized: tables with columns, primary and foreign keys, indexes, approximate row counts, and comments. Only tables and columns this credential may see are included; masked columns are flagged. Paginates for large schemas.

postgresdatabasesqlmcp

my_permissions

What this credential is allowed to do, so the agent does not learn its limits by being blocked: access mode, permitted statement kinds, table allowlist and denylist, row-filtered tables, masked columns, budgets, and how writes are routed. No arguments, no database round-trip.

postgresdatabasesqlmcp

search_docs

Search the PgBeam documentation and return matching pages as {title, url, snippet}. Find how PgBeam works: connecting, masking, query budgets, the kill-switch, and more.

postgresdatabasesqlmcp

read_doc

Return the markdown of a single PgBeam documentation page by slug or url (chain from a search_docs result).

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: PgBeam — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Auth schemes: agentCredential
Extensions: https://pgbeam.com/bindings/mcp-streamable-http/v1 — required of clients
The interface above is a Model Context Protocol server over Streamable HTTP. Connect with an MCP client, authenticate with a scoped PgBeam agent credential, and call the tools listed as skills. Full connection metadata is in the MCP server card.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
